What new opportunities can come about if we were able to, you know, open the eyes and see magnetic fields rather than seeing light or what does that open up and how can we harness that? So that's kind of like the concept that how we're thinking about detect. Imagine a world where computers don't just calculate faster. They think in fundamentally new ways. That's the promise of the quantum technology industry, which is a billion-dollar industry projected to be valued in the hundreds of billions by 2040. Why should you care? because quantum technology could reshape the world. From drug discovery to financial markets,

supply chain logistics to advanced materials, quantum tech promises tools that could solve massive optimization and simulation challenges in seconds, problems that would take today's computers millennia. This isn't sci-fi, the foundational science is already real, with companies and governments pouring billions into research and development. This episode is going to be a little different than usual. We're diving into the world of quantum technology,

which means we'll be tackling some complex ideas and using words like magnetometers and cubits. I promise you'll learn a lot. Today's guest is Dr. Jim Rabot, an international leader in quantum technology and innovation. We're making quantum mainstream by connecting it with these semiconductors superhighway. With a PhD in physics and a career bridging deep science, entrepreneurship and industry, Jim has spent decades turning breakthrough ideas into practical technology. You bring in AI in quantum. There's a lot of consideration about what the impacts are going to be.

He's the CEO and co-founder of Detect, an Australian startup that's revolutionizing navigation through quantum magnetometers. Compact, diamond-based sensors that bring quantum precision into the real world. Out of a lab into the commercial opportunities. Get ready. Today's conversation will teach you about the latest technology you won't want to miss out on. All right, guys, I'm really excited about today. Welcome back to the Mello Millionaire. Today's guest is a world leader in quantum technology and innovation.

With a PhD in physics and a career bridging deep science entrepreneurship and industry, Jim has spent decades turning breakthrough ideas into practical technology. Jim, it's a pleasure to have you on today. Nice to meet you, Tommy. Thanks for having me. So let's just, I don't know if there's an easy way to explain what you do, but tell us a little bit about the journey, what you're doing today and what you're excited about. Okay, well, let me go back.

quite a ways to the PhD. That's what really started things off in terms of the science and tech that I've been passionate about for about 25 years. In my PhD, I grew diamond films in a lab, so basically turning gas with carbon in it into thin layers of diamond. There's lots of interesting applications for that, electronics, hard coatings on drill materials, blades and so on, and thermal conductivity. But at that stage, early 2000s, there was a lot of excitement and growth in the quantum, especially quantum computing. So how can you use quantum objects, quantum particles to do really powerful computation? So that got me into applying, you know, the diamond materials to learning how you could use them in quantum technologies. The work I'm doing is more around sensing and

magnetic field sensing. So there's all these things that we're, we can kind of tap into either developing technologies to measure or effect magnetic fields to do interesting things. But what's really fascinating to me is how we weren't designed and we didn't evolve to be able to see or measure magnetic fields as humans. But animals, some animals can do that, right? And so birds and turtles have this ability to navigate with magnetic fields. And the turtle example is kind of the most interesting to me.

You know, a turtle hatches on the shore somewhere. And it's able to imprint this, you know, these magnetic features that I was talking about earlier under in the Earth's crust. So not just saying, okay, here's north and south, but rather they can imprint kind of this map. of where they were hashed. And they go and they swim, you know, to the other side of the world. And they're able to find their way back because of the ability to sense these fields in the earth and find their way back to, you know, roughly the place where they were, where

they were hashed. It's not fully understood the physiological mechanisms that make this work. But birds as well, they can, you know, navigate themselves. in different migratory patterns, but they can orient themselves quite accurately to magnetic fields. And so it's just fascinating how if you think about, you know, the human body has sensors, right? You can you can open your eyes and you see the world around you and you see that because light is coming into our eyes. Now imagine, you know, what animals are doing or imagine being able to,

open some sensory mechanism and be able to see magnetic fields. And what does that open up for us? Right? I mean, we know that animals have some way to do that essentially sense fields and they can navigate with this. So this is kind of this kind of concept that that we're thinking about as saying, well, what does it open up? What new opportunities can come about if we were able to, you know, open a, you know, the eyes and see magnetic fields rather than seeing light. what does that open up and how can we harness that? So that's kind of like the concept that how we're thinking about detect and making our sensors small and deployable

that we can start to see fields that we haven't seen before, whether that's in the human body, underground, for, you know, different applications. So basically the earth is a big magnetine. It's got metallic material kind of spinning around and that creates a current. And so we have this, it's like a big magnetism, it with a north from the south.

And that just is pervasive, right? Like through this room right now, there's magnetic fields traveling. We can't see them. And they're used in technology in many ways. Like a hard disk uses magnetic signatures and sensors to save data. I always had this entrepreneurial bent and decided to leave academics. And I worked at Deloitte as a consultant. And I just was moving around.

and in the business world and trying to learn, build networks. That brings us to today where I'm now the CEO of a startup company called Detect. We're developing a magnetic field sensor that has a whole range of possible applications from navigation to mineral exploration to medical sensing. Quantum mechanics, there's two kinds of descriptions of the world. There's classical mechanics. It describes the way the world that we can see around us, the way it works. So it's enabled us to, for example, build planes that fly because of, you know, the forces that work.

So very functional, accurate at a macro, at a large scale. Over the last 100 plus years, we've started to understand things at the really, you know, that's a small scale, like the scale of electrons, a scale of single particles of light. And it turns out, so that's called, that's the quantum world, so quantum mechanics. And things behave much differently at that scale, right? You can't predict as easily as you can like a tennis ball. So if you imagine shrinking a tennis ball to like, you know, the size of an electron, which is incredibly small, electrons behave in different ways.

There's certain characteristics like superposition and entanglement. These behaviors, if, you know, people are. really started to think about them probably in the last 30, 40 years about, well, what could you do with these if you could harness them? And that's what's led to things like quantum computing. You can do, you know, really powerful computation much better than, you know, just using zeros and ones like we do in our computers now. So, so that's one thing. Another thing that you can do is these are very fragile states of matter or light. If you can tap into them, you can use them as sensors. So now imagine being able to like, you know, look at them with a technology that we

build around it. And then each time a magnetic field change is really, really small, a really subtle change, you can detect that. So quantum is just a kind of a tool that enables us to tap into the world around us in ways that we haven't been able to before. And that includes computing, sensing, communication. So those are the three sort of big pillar. is this rigid crystal and structure that has these quantum objects, nitrogen atoms, trapped inside it. We can actually use that crystal as a sensor of magnetic fields, again, building electronics and optics around that. Right at the beginning of COVID, 2020, you got a grant from the Australian Defence Force. We've designed and fabricated a tiny silicon control chip, much like what you get in your phone or computer.

that interfaces with our quantum chip. So we have two things. We have the quantum sensor, and we have this semiconductor, which is really mainstream, very scalable, putting those two things together, and now we have this technology that can measure magnetic fields.

So you've got communication, navigation, and detecting. Do you want to just give me a summary of each of those, how it works? Here's how this works. Right now in the Ukraine, there's no satellite connection. Satellites are there, but they're being jammed.

So in conflict zones anywhere, really, the satellites become inaccessible. The same thing happens in a tunnel. When you're driving somewhere, you got your GPS going, you go into a tunnel, you lose that line of sight, so suddenly you don't have accurate navigation.

In fact, you don't have anything. It's just sort of guessing where you are. Underwater submarines, they don't have a line of sight to satellites, so GPS doesn't work. So in these different scenarios, like whether you're underground, or underwater or at a conflict zone where satellites are basically being knocked out,

you can't navigate reliably with GPS. So this is a pain in the butt when you're trying to navigate to a new restaurant or something in the city and you go in a tunnel and you get lost. When you're in a conflict zone or when you're underwater with a big submarine, it's not just a pain in the butt. It's actually very problematic. So there's this urgent kind of pressure right now, or military, globally, to solve how do you navigate without GPS? Getting into how magnetic field sensing and the tech that we're developing, which is all about measuring magnetic fields.

How does that come into it? Well, the Earth is just like this big spinning magnet. These are big strong fields. Now, what happens in underground where there's blobs of metallic? metallic objects and different things. Basically, those field lines kind of get wavy and they move around. Like they, there's, there's texture to them. What that then looks like for us on the surface is that those wobbles and things that,

you know, around these objects underground create essentially a map, a magnetic field map. Now we have a way to sort of say, okay, here's, here's the surface of the earth, rather than thinking of a roadmap. Well, you've got this magnetic path. that you can follow because you know that if you have a map of what those magnetic anomalies are, you can use that to locate yourself with a sensor on the grid, if that makes sense. So essentially replacing a roadmap with a magnetic field map and then using a magnetic sensor kind of to track yourself around. And that's a completely independent of satellites.

You can actually have something in your hand. Like I'll just hold up my phone here. It's like our device currently is around this size, you know, a bit thicker, but it measures the magnetic field. So if I have a map in my hand on one side and my sensor here and I can link it to the map, you can then navigate without GPS. And that's hugely valuable, especially in the military context, it makes them independent of satellites. So there's a real security aspect there that they're drawing for.

It sounds groundbreaking. I mean, it sounds like if you, how far a lot? are you as far as dependability? Is like, what phase are you in? There's been demonstrations done by others, other technologies to demonstrate that you can get GPS level precision with magnetic field sensing, quantum magnetic field sensing specifically. Where we're at as a company's, we've kind of taken a slightly longer path and really focused on the hardware and the scalability.

And that's where semiconductors come in. So our effort has been on designing and testing a chip, millimeter scale chip that we interface that we connect with the diamond. And that is solving one of the biggest challenges for all of quantum technology, and that's scalability. Like, how do you make a lot of these things at a reasonable price point? And because quantum tech is so complex and sophisticated in terms of the, the technologies that you need to integrate together, this is a big kind of roadblock.

The next steps over the next 12 months and what we're raising this C funding round for right now is to really focus on testing it out in the field. Yeah, I'm very, very interested in that because I'm just thinking about, like, as you know, Venezuela has some of the most resources around. And you're basically building kind of a treasure finder in a lot of ways. It's like we're moving the base technology, technological capability in certain areas beyond what we've ever been able to do before. And when you do that, you're going to discover new things. You're going to enable new things. And this is why in the commercial world, these new valuable things are starting to

be emerge and people want to get on board. And so that's why, you know, 20 years ago, investors wouldn't really have looked at too closely at quantum tech. But now it's becoming more. tangible and real. You know, magnets seem to be a hot topic. I know that China has kind of really reined in a lot of the magnetic development. Let me ask you a few repeat questions I ask. And I'm just curious, if you could go back and talk to yourself in your early 20s, what piece of advice would you give yourself?

That's a really great question. In my early 20s, and this is something. I'm still learning is, or you're not alone in making mistakes. The idea of, especially being a CEO of a startup, it can be kind of isolating, right? And you're going to screw up. You're internalizing that and saying, I've failed at this, and, you know, that can really drag you down. But I think it's really important to actually embrace it and understand that you're not the only one who's gone through and hit walls and made a mess of things. but I'm certainly still learning.

The older you get, the more you kind of are aware of yourself, I suppose. I was going to ask you, so as far as what you're working on today, what does success look like? What does that mean? If you were to look back in 30 years, you'd say that's what I made it. That was it. You know, one answer is that I exit or we list on the stock exchange or I exit, somebody acquires a company and we make 100 million. For success of the company,

I would love to, what I want to get to is that our device, our technology is taken up in real applications broadly. We want to make a magnetic field sensor that's going to open up something that we're calling magnetic field intelligence. So it's like ubiquitous deployment of sensors that can tap into information all around us

because magnetic fields are all around us, right? So that's for the company, that's what I want. want to get to. For Jim, the answer for what does success look like for Jim, I think about this every single day. I've got three kids. They're in their 20s. I've got parents in Canada. I want to see them at Christmas time, siblings over there as well. It's about looking back and saying, I made the right decisions when it mattered. I chose the right things that really matter. and figuring out what those are is actually a little bit more challenging, but not choosing to

forego the things that are important like my kids and family and so on because of the success of detect. And I think, again, as you get older and more self-aware, I think that's probably an easier judgment call to make, but I certainly don't want to end up in 30 years saying, damn, you know, I wasted 15 of those years, not having the time that I really would have loved to have with the kids. So that's how I want to answer that, Tommy. I think it's having that balance. Because in order to be successful, you do have to forego some things. It's just where's that line? And so just as an example, I was exhausted yesterday at the end of day, but my son and I went and saw ACDC. I've never seen ACDC before there here in Sydney. And he's 21 and

blown away. We went and I, you know, I was I was kind of like, oh, geez, I wish I had the night in. But but ACDC and my son, you know, we're sitting there taking this in and and I don't think we'll ever see them again. And he was videoing, you know, the different songs that we've been listening to for the last 15 years together. And it was just the best, the best thing. And I'm like, I'm so glad this hop it. I love the answer and you're right. There's going to be sacrifices. The best advice I ever got was be where your feet are, be all in. And it's hard for entrepreneurs to not be thinking about what we're excited about, even though we're all excited about our families. It's just, there's so much work to be done. But then all of a sudden, a year goes by and then a decade goes

by. You're right, there's a weird balance and it's off balance and I think that's okay. What are your biggest challenges? I think that's the number one challenge in building the company is putting the required time and effort and diligence into recruiting the best people, but also having the culture defining and having the culture that enables you to be a magnet for great talent. I was fortunate very early on in recruiting. I got my COO on board and she's just been phenomenal at kind of doing all the things that I'm not good. You know, where I'm kind of in this direction and high level. She's very much operational and structure and has just been ticking the box and all the different things that we need to build to have a strong foundation of company and then become that magnet. And then, you know, learning this very early on, and it's really hard,

it's like literally really early on when you're sort of a handful of people, recognizing when you didn't hire the right person. And so what do you do with that and how do you address it? And being a leader and taking a hard decision for the good of the company. So there's like, you know, hiring the best and then making sure that you don't hold on too long to somebody who you realize is not a fit. A B player is the worst employee because they're never going to take you to where you need to go, but they just do enough to kind of stay alive. But A players don't like B players. And they're going to, you're going to get worse performance out of the A players by keeping a B player.

But B players, they kind of are incognito. You don't really see it, and it's really hard to see it, but you can almost tell by the way the A players are performing that they're holding them back. One of the questions is quantum sensing market is projected to be a $6 billion industry by 2040. Which industries do you believe will be impacted first? I think that navigation is probably the earliest one where we're seeing the most traction and mining. So those two things kind of go hand in hand in enhancing our ability to find critical minerals underground. I think as we push the boundaries out further, the technology gets more advanced. I think I'm really, really excited and I think it's a huge, you know, beyond those numbers, a huge market opportunity and huge benefit potential is the medical diagnostics space.

I mean, the human body has so much electrical magnetic information signatures that, well, like the heart beat, do an ECG, and you can learn a lot about how the heart is, what the heart rhythm is, and you can diagnose things. MRI, magnetic resonance imaging is, I mean, you might have you had one of your ankle, I don't know, but so that enables you to see the density and the, you know, changes and injuries in, in the human body. that you can't measure with x-ray. There's so much information there. And if we can push the boundary of what you can measure a little bit further, and then it opens up new information, new, more rapid diagnosis, so on. So that's something that I'm also really excited about. What are your thoughts?

I've talked to a lot of people in the past that are just light years ahead of my IQ. But I feel like I'm just curious your take on this because there's EQ which is emotional intelligence and then there's just like photographic memories and people that just understand the deepest comprehension of certain things. I've worked with a lot of people who you know like my IQ is not near

the level of a lot of people that I've worked with over the years who are quantum or physicists or scientists who are really understand deeply understand things and can see things in numbers or in data and interpret in ways that, like, I could never get to. With the, you know, the cases is that the EQ broadly defined is more lacking. Like, you know, it's communication. How do you, like communicating a hard topic, right?

That might be really challenging for somebody with that very narrow, deep IQ. What I'm trying to do is when you're trying to bridge both, right, like you're trying to bridge something that is deep quantum or deep technology, which is just called deep tech, with the EQ requirements of running a company and building that team that we're talking about and becoming a magnet and having the culture. What's one thing you wish more people understood about quantum technology? Quantum is a fundamental way that the world works, right? It's like it describes how the world works. So it's fundamental. We're tapping into that in ways that enable us to do things that we have

never been able to do before. For example, like sensing something that you can't sense with normal sensor. How is AI going to affect your research going forward? AI is a basic, like, I just can't believe how fast things have moved there. So we're using it in the company to help, whether it's understanding or, you know,

accessing a wider range of perspectives on a certain technology problem or, you know, how do we communicate something better in terms of like our sensors and the types of data that we're going to be pulling in, we'll certainly be looking at using AI to interpret that and enhance like what the overall solution to a customer might be. So I think for us, it's like trying to leverage it as much as possible in both in the business side, but also in the tech tech side. The world could be so small. If you

just think about money and business and corporate development and just the things that it look, you know, it's just expand your horizon. And this was so fun to just learn about what's possible and what intrigues guys like you because it's just the world's going to be

changing so much quicker. I mean, 3D printing and what we're exploration. Like there's nothing more, we're building a place in Sanpoint Idaho, which is really far north near Canada, and just looking at space and just thinking, wow, like, beyond ourselves. Do you ever just, I don't know what, though, I didn't really do any stargazing in Australia when I was there, but do you ever just look at places and you're like, wow, we're just, we're at the cusp of just learning so much

more? I had the same, literally the same thought we were at this ACDC concert yesterday. And I was thinking, you know, like I've got all these, I had a lot of my mind. I'm thinking about solving, you know, negotiations and all this. And we were sat up on like the second tier-ish, so looking out over all the people on the, on the floor and in the stands. And I was, I just almost had that same kind of stargazing moment, but in reverse where you're looking at all these individual humans down there. And it's kind of like all those people.

having different perspectives on the world. And it also gives you the similar view of, like, in some ways, like, how insignificant your little world is. But yet so important to yourself. I love, I love that visual of the end, and shrinking down to this, you know, to this, you know, imaginary kind of like universe of things. I love that stuff. You know, I'm very cautiously optimistic about AI and I'm not like the end of time or anything. but it's definitely I'm ready for it and I accept change and I'm more of a first implementer. Like I love to go deep into things and like not be afraid.

But yeah, I just, there's so much to think about. And, you know, unfortunately and fortunately, I've been very successful with business, but there's so much more. So let me ask you this. We'll wrap up here. what is a book that just means a lot to you? I'll tell you the book. I'll tell you the book that I really found impactful. Is Eckertoll?

He wrote The Power of Now, and he also then followed that up with a new earth. And my mom gave it to me like 20 years ago or something. And I think she, I've got three brothers and two sisters and I think she gave all of us a copy of that book, a new earth. It's more about like consciousness and humans and being in the present, right? Like some really powerful kind of like ways to approach being in the present. And I just found it, especially sort of through the time in my, you know, in my 30s where, you know, there's challenging stuff. You're raising kids and you're trying to do your career.

and I just found it really powerful to help me. And I still go back and read bits of that, bits of that book. What's the one by Never Split the Difference? Yeah, yeah, which I've also heard about for a long time, and I picked it up not long ago. And I just, it's pretty, you know, great read. That one I did read end to end. And, you know, you probably need to read that several times

to really embed all the components. But yeah, that was really, really interesting, really useful as well. Yeah, if you ever want to meet Chris, I've got to know him really well. He's out in Vegas. He just was with me at my last event. So he's a fun guy. Awesome.

And then we talked about a lot of cool stuff. I never thought I'd be as into electromagnetic sensitivity. But we'll let you close us out on anything you want to wrap us up here, brother. Well, I just want to say, Tommy, it's awesome. to talk to you. Like, I admire that you've, you know, you're, like I said, pushing the boundaries and diving into something like this. And I think we're at this exciting time of quantum technology that he's kind of like, you know, it's been in the lab and a research thing for many, many years. And we're really at this precipice of saying, okay, what can this really do in the world around us?

And so I was excited to share that with you. And thanks for, for content. contacting me and setting this up. Yeah, I definitely want to stay in communication. I want to see how this all comes together and I'll be praying for you. I mean, look, it sounds like you got a good grasp of everything. You've got a strong team. But I think you're in the beginning stages of something that's going to be super fun. And, you know, when you look back, it's your building.

I always like to say, like, I'm fascinated with Back to the Future. I have a Dolorian that's made up like Back to the Future too. and you're like, where you're going, there are no roads because you're building your own roads, so it's going to be awesome. I love that. Delorian, man. I think if you ask me that success question again, I would love a Delorean.

If you get out of the Phoenix, come visit. I'd love to have you out here, and you're more than welcome anytime, and I'd love to take you for a ride. I'm getting an electric motor put in it just because those motors weren't super reliable. So now this thing will do 0 to 88 in about 6.8 seconds. Amazing. That's so good. No, I definitely will keep in touch. And yeah, from ever in the neighborhood, I'll ping you. And yeah, thanks again. Appreciate the chat. This is a great podcast. Thanks for the listeners for listening. Hopefully you got something out of this. And I hope you guys are having a great day.

Thanks so much for listening to this episode. Like always, we're going to close it out with the Tommy Truth, which is a little slice of wisdom from me to you that can help guys. you in whatever you're striving towards right now. Do you know less than 5% of businesses ever across $1 million in annual revenue? Your chances are 1 in 20. And the reason why is most people underestimate what they can do in five years and overestimate what they could do in a year and they give up. There's a great book about this called 3 feet from gold. And the best answer I could give to you is don't give up, make a plan, reverse engineer it, and stay the course. Go for the long term. Start to learn how to

teams and not be so reliant on yourself. Businesses that track key performance indicators grow 60% faster than those that don't. When you know the score, it's a lot easier to win the game. And that's it, guys. We'll talk to you next week.
