The Genius Behind the Quantum Navigation Breakthrough

This is the World's First Unhackable Quantum GPS. Using the coldest atoms in the Universe, it may revolutionise the way we navigate. I got to go behind the scenes and see their device up close to try and understand just how important this breakthrough is.

Fun fact, I said Bose-Einstein Condensate 284 times during this video... did you catch them all?
Massive thank you to Infleqtion for showing me around behind the scenes! Not a sponsored video, just thought this was awesome and I wanted to learn more.
Channel and Patreon members 👉I'll be posting a little bit of further BTS scenes in the next couple of days
Thanks to everyone for your support 🙏🙏

For worried fliers, passenger aircraft already have good IMU systems to back up GPS, just not ultra accurate quantum IMUs yet. Jammed or spoofed GPS is annoying to pilots, but not necessarily dangerous. If it wasn’t something they couldn’t safely handle passenger flights would be canceled in those areas.

I can't believe I've heard of laser cooling about a hundred times without hearing the term "Doppler cooling", which means I just ACTUALLY learned how it works, instead of just hearing it described to me.
Thanx!!!

The Condensate knows where it is by knowing where it isn't

ICBMs have always used Inertial Motion Units. That’s why early ICBMs had multi-megaton warheads because they were only accurate to within a few kilometers.

As a 767 airline pilot that was spoofed and jammed on 12 separate flights around Eastern Europe and the Middle East, recently. I was very happy to have our IRS (IMU) backup(old school cool). This is one of the best videos I've seen this year.

The fact that I, a relatively simple minded person, not only understood every word used in this video. Fully grasped the fundamental concepts used to achieve the desired result in the experiment, and ultimately understand how they work together to provide the desired results. Well that just blows my mind.

We definitely need a follow up on this, because Sandia National labs have accomplished a miniaturized, ruggedized version of the same mechanism on a single 8mm piece of silicon, with 100, 000x less sideband noise. This technology is moving INCREDIBLY rapidly.

GPS is also used for calibrating clocks. False GPS signals cause naive clocks show the wrong time. Causing havoc in many technical systems, including the Ukrainian electric grid, I've read, until they fixed this unnecessary vulnerability. Just jamming doesnt do it, but spoofing does. Simply resending a GPS signal, making it reach receivers later. No decryption needed.

This is almost like taking a ball of mercury and holding it in a "Center" placement via magnetics and calculating its position by its inertial displacement, but on a quantum level. Brilliant!

[aterxter]

I just pocked the video out of curiosity and oh boy, such a good vulgarisation.
You have really struck the good balance between explaining completely and simplifying to let people understand.
I see it as I worked a lot around IMUs, your video has it's approsimations, but it's definitely worth it.
Thanks a lot

"Fits in the palm of your hand" fits in the guidance system of a missile. Unjammable ammo is a gamechanger in a peer to peer combat scenario.

In scientific terms, this is called "that's insane bro"

[j.d.]

This is absolutely amazing!
I am no quantum physicist, but as an amateur engineer I feel much appreciation for the beauty of this design.

[i-xploreAdventures]

It's amazing what videos you stumble upon on Youtube. This was incredible. I had no idea. I learned so much. We know a lot but every time there is some breakthrough it really shows actually we know very little in the grand scheme of things. Great video!

Do not be embarrassed by your mistakes. Nothing can teach us better than our understanding of them. This is one of the best ways of self-education.

Submarines don't use dead reckoning with inertial navigators alone, they use gradiometers and plot the variation in the measured graviational field against a reference Geoid. The data are measured by survey ships and provide continual passive position fixes from maps of the gravity field without any requirement to receive a signal. American and British ballistic missile submarines have been doing this for the last forty years.
Inertial navigation isn't just about sensor accuracy, it is also requires exceptional dimensional stability. The most precise navigation systems are manufactured from beryllium which brings a whole host of cost and complexities that make it impractical for all but the most critical applications.
Inertial navigation is not a replacement for GPS, there continues to be a requirement for position fixes in navigation, just as mariners used a sextant to improve the accuracy of their measurements.

@11:00 Fun fact for the viewers at home: Take your cellphone and bring up the camera app. Then point your TV remote (or any IR remote control) and point it at the camera lens and look at your screen. Your camera can see the near-infrared flashing LED, even though your eyes can't see it. (I use this technique to see if my batteries need to be changed)

I first learned about laser cooling back in highschool when reading about researchers who had "trapped" light in a BEC. The article I read explained the whole process almost as well as you did in this video and it made me realize just how crazy/important the invention of the laser was for scientists. Like, every single step involved several lasers: pre-cooling the gas, moving the gas into the vacuum chamber, dopler cooling the gas until it becomes a BEC, one laser excited the gas so it reacted to another laser being reflected in a loop. Shortly after, scientists discovered how to make "optical tweezers" and I learned how atomic clocks work. Lasers are feel like a tool brought to humans from mount olympus or something...

idk, I used to be a cartographer (I made the 3D map on your phone), and I've worked with GPS and NASA's GPS kingpin, but I think GPS is not trilateration, it's a quad deal, and the reason is the GPS receiver in your pocket is not an atomic clock, so you got lat, Lon, height, and your clock bias to solve: 4 unknowns.
