Processing quantum information with relativistic motion of atoms

TL;DR

Non-inertial trajectories enable arbitrary quantum rotations.

Relativistic effects can be harnessed for quantum gate implementation.

Particle detectors in gravitational fields can process quantum information.

Abstract

We show that particle detectors, such as 2-level atoms, in non-inertial motion (or in gravitational fields) could be used to build quantum gates for the processing of quantum information. Concretely, we show that through suitably chosen non-inertial trajectories of the detectors the interaction Hamiltonian's time dependence can be modulated to yield arbitrary rotations in the Bloch sphere due to relativistic quantum effects.
