  High-precision gyroscopes are a key component of inertial navigation systems.
By considering matter wave gyroscopes that make use of entanglement it should
be possible to gain some advantages in terms of sensitivity, size, and
resources used over unentangled optical systems. In this paper we consider the
details of such a quantum-enhanced atom interferometry scheme based on atoms
trapped in a carefully-chosen rotating trap. We consider all the steps:
entanglement generation, phase imprinting, and read-out of the signal and show
that quantum enhancement should be possible in principle. While the improvement
in performance over equivalent unentangled schemes is small, our feasibility
study opens the door to further developments and improvements.
