Sorry, Allen, but quantum or not, a gyroscope measures change of orientation
and accelerometers measure accelerations - those accelerations can only be with
respect to an inertial frame. Both a free-floating, constant (but any) velocity frame
and one free-falling in a gravitational field are inertial frames. That has been
confirmed by observations over and over again. Ask the crew on the International
Space Station, for example.
Eh, - and how would you measure a constant velocity (is part of your "any motion")
with an accelerometer or a gyroscope, for that matter?
