Okay, well, let, let me go back quite a, 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 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, you know, 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. The most interesting to me. You know, a turtle hatches on. 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. Like, so not just saying, okay, here's north and south, but rather they can imprint kind of this map of the. Where they're hatched, and they go and they swim, you know, to the other side of the world. And, 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. The place where they were, where they were hashed. It's not fully understood the physiological mechanisms that. That make this work, but birds as well, they can, you know, navigate themselves in. In, you know, different migratory patterns, but they can orient themselves quite accurately to magnetic fields. And so the, you know, it's. It's just fascinating how if you, if you think about, you know, the human body has. Has sensors, right? You can, 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 or what does that open up? And how, how can we har 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 different applications. So basically, the Earth is a big magnet. It's got metallic material kind of spinning around and that creates a current. And so we have this. It's like a big magnet with the north and 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 in the business world and trying to, 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, so it's enabled us to, for example, build planes that fly because of, you know, the forces at work. So very functional, accurate at a, at a macro, at a large scale. Over the last hundred plus years, we've started to understand things at the really, you know, the small scale, like the scale of electrons, the scale of single particles of light. And it turns out, so that's called, that's the quantum world. So quantum mechanics. And that things behave much differently at that scale. Right? You can't predict as easily as you can like a tennis ball. So if you, if you imagine shrinking a tennis ball to like, you know, the size of an electron, which is incredibly small, electrons behave in, in different ways. There's certain characteristics like superposition and entanglement. These behaviors, if, you know, people have really started to think about them probably in the last 30, 40 years, about what could you do with these if you, 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 in. In, you know, just using zeros and ones like we do in our computers now. So, 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 changes, 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 there's a. Those are the three sort of big pillars. There's this rigid crystalline 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, you know, electronics and optics around that. Right at the beginning of COVID 2020, you got a grant from the Australian Defense 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 tunings together. Now we have this technology that can measure magnetic fields.
