Re. quantum navigation system (QNAS) ?
Is this actually a thing yet?
I did come up with a design for a GPS-less parcel tracking system, that is patentable but unfortunately can't develop it due to an annoyance called the Invention Secrecy Act.
Very similar concept and can make it work using less than £1 worth of parts, has a neural network based on a very *very* cheap micro but with some tweaks to get adaptive navigation even indoors.
The fiddly part is optimizing code for low power and high accuracy at the same time.
I estimate based on measurements here that it should be accurate to +/- 75m minimum but thats fine for most applications when in fact 300 metres is more than good enough.
If anyone wants to know more I can be contacted via my backup number ie +44 778* ******
