Speaker 0: the ocean has been the ultimate hiding spot for a century, but quantum physics just turned on the lights. china's new drone mounted sensors can now see through the deep, and the air of invisible submarine is officially on life support. quantum sensors have just killed submarine stealth. the new quantum magnetometers and gravimeters can detect the microscopic magnetic and gravitational ripples caused by a submarine's hull. china has recently proved this works using a low cost drone that matches the best tech nato has to offer. this compromises the nuclear triad. if submarines can't hide, they can't access as secret deterrent fundamentally shifting global military balance. what do you think about this, john? Speaker 1: i love this. i love this new quantum tech, all these new sensors that are coming out. this is really cool stuff. and the question is is this just limited to underwater? is this going to eliminate radar completely even for planes and all that sort of stuff going forward? because so let's dive into this real quickly, though. so the reason why submarines have been historically undetectable is because they rely on acoustic stealth, which is ultra quiet propulsion, shape design to reduce their solar reflections, and operating in noisy ocean environments. and so traditional detection methods were solar, so sound waves, radar, which is kind of ineffective underwater, and magnetic anomaly detection, which has limited sensitivity. so modern submarines like nuclear ballistic submarines, they're designed to be so quiet they blend into background ocean noise, which makes them nearly invisible using classical techniques. the way that this quantum sensing breaks the stealth is from a completely different angle. so instead of detecting sound, they detect mass displacement in water, so gravitational changes. they, they detect magnetic signatures from metal hulls and disturbances in earth's natural fields. and i know we kind of covered some of this stuff in the past, but this just shows a practical application of some of those sensors that we covered. so even a perfectly silent submarine, there's three things that it has. well, more than that. but mass, it alters local gravity slightly, and it disturbs magnetic fields. so these effects are impossible to eliminate entirely, which is why this is potentially so disruptive. and so if we talk about the, the way that these sensors work, do you like, would you not think that they could adapt this to planes in the air? or what are your thoughts on this? is this more magic? you're on mute. Speaker 0: i don't know if they can adapt it to planes in the air for a couple of reasons because i think part of it is, they're detecting, like, the slight movements in the water on top of the magnetic, on top of like, this is according to research, squids could detect submarines from 3.7 miles away compared to, point five, miles conventional, and would they have the potential range of six kilometers? so we sit back and say they're looking towards a transparent ocean as early as 2050. but that means they've got to put all these magnetometers and squids and gravitometers gravimeters set up all over the place to have the transparent ocean. so how do you do that in the sky? well Speaker 1: okay. yeah. that makes sense. Speaker 0: so until we have enough satellites to be running these kinds of things in the sky at a six kilometer plus range, and that would, you know, blacken the sky probably or whatnot with all these things. so i think we're gonna have different types of detection via the satellite network that they're building for whatever is going on above ground. Speaker 1: yeah. and here's the thing, though. so despite the hype that what this could potentially do, there are some real limitations. so many of the quantum sensing systems, like, work only at short ranges, like you said, or controlled conditions. and ocean environments are extremely noisy. so thermal magnetic and geological noise. and scaling sensitivity to long range detection right now is a major hurdle. so even in related technologies like quantum radar, long range detection remains largely theoretical or speculative at this time. so, in nowhere in the near future are is this tech going to be usable tech, in the next, i'd say, five years. maybe ten. Speaker 0: yeah. so these drones are tethered via a 20 meter cable to a cpt magnetometer keeping it isolated from the electromagnetic interference. so these things have to be distributed. so that's why we wouldn't have them in the sky. but it's really like, to think of this update like trying to walk through a dark room filled with suspended glitter. you might be silent and invisible, but your body naturally pushes the glitter aside as you move. these quantum sensors don't look for the person. they look for the glitter. the tiny disturbances in the earth's magnetic field to tell them exactly where you are. yeah. so it's like, i don't know. every time the, in star trek, we have to collect the klingon, cloaking, we're detecting radiation signals or disturbances. we can't detect the ship itself. Speaker 1: yeah. so Speaker 0: its accuracy is point eight four nine nanoteslas. do you know what a nanotesla is? no. i'm trying to see if i have it here. the squid can hit 3.7 miles. we talked about that. it's a reliability of 99.8%, and the sensitivity is picotessla range, which is one trillionth of a tesla. so okay. anyway, these are extremely sensitive. the squid super con conducting quantum interface interference devices mentioned must be cooled near sub zero, absolute zero negative 273 degrees celsius requiring advanced cryogenics packaging in the mobile unit. while china is making headlines, the us launched darpa's robust quantum sensors phase one in august 2020 sorry, 2025, essentially confirming that the pentagon is in a black project arms race to catch or surpass these findings. so they've got their own thing going on that there we don't really, know about. the earth's magnetic field in the south china sea is nearly parallel to the surface, which usually creates a blind spot for magnetic sensors. china's cpt system was specifically designed to exploit this unscannable zone. Speaker 1: crazy. Speaker 0: so the silent service is about to get very loud as quantum physics makes the haystack smaller and the needle glow in the dark. if the ocean becomes transparent, does the submarine become a $3,000,000,000 coffin, or can tech, like magnetic jamming, save it? drop your theories in the chat. we'd love to hear what you think.
