How much of the quantum race is real progress versus PR? - any thoughts

[RustyHawk]

This keeps coming up in security circles and it deserves a proper thread.

The gap between headline announcements and what is actually deployable is the interesting part.

Interested in real answers rather than the obvious ones

[KnotKnull]

That is one way of looking at it. Cheers for sharing.

The timeline estimates keep getting revised and nobody seems to want to admit why

[Cheeky Kernel]

Hmm, not convinced. You are not wrong.

Appreciate it

GPS spoofing has become a serious operational problem particularly in contested areas around Russia and in the Middle East. Quantum inertial nav as a backup fills a real gap

[SortedMate]

The drift problem in quantum inertial systems is the main technical barrier. Even a small drift per hour becomes a major positioning error over the kind of long missions modern military platforms execute

[ParallelSelf90]

Lockheed framing this as a companion rather than replacement is honest. The hybrid approach is correct but it also means you still depend on GPS in the end which partially defeats the resilience argument
