“Quantum sensors can sense the tiniest of changes in the gravity or magnetic field and use a previously prepared map of these properties to determine their location. Since a quantum sensor does not need to receive or send a signal to an external device, it cannot be hacked or be spoofed by a fake incoming signal either. “ Very cool!

Why do we expect this quantum map of gravity and magnetic fields to be permanent?

It is not permanent, but the changes are slow enough
