I thought I'd share with you an excellent discussion between some physicist and some other physicist who is trying to get quantum navigation to work. We don't get the full details of the mechanism, but the reason it is called quantum is it is an inertial navigation system where instead of using lasers to measure changes in distance via interferometry they use a Bose Einstein condensate. Apparently this works similar to the laser system but the wavelength of the BEC is very much shorter than the laser light and so you can get an accuracy thousands of times greater. There are some caveats though. The goal is to be able to set the system to the location you are currently at, and then by measuring accelerations to a very high accuracy the system can plot your course without taking a fix. Doing this gives you a cumulative error no matter which way you do it, but small errors are better than large ones. However it is not as simple as just upping the accuracy of the accelerometers since other errors in navigation give much higher errors. Mind you it still has potential uses with satellites where the satellite can see into the earth and find all those deposits of gold and oil etc. These things are super sensitive.
By the way, this a rare find. This is a British bit of research.

Of course it will certainly be used by the US military to keep one jump ahead of the Russians and Chinese. The Office of the Secretary of Defense is requesting $75 million in fiscal 2024 to initiate a brand new pursuit intended to both accelerate the commercialization and operationalization of quantum devices for Pentagon purposes, and mature the U.S. supply chain underpinning the making of emerging quantum technologies. I have been studying QIS for several years and it is certainly a game changer and very remote and constructive area of physics. I think the most compelling ospin-off will be chemistry for advanced energetics, propulsion that is my OPO on this vast subject
