Quantum gates via relativistic remote control
arXiv:1404.5308 · doi:10.1016/j.physletb.2014.10.038
Abstract
We harness general relativistic effects to gain quantum control on a stationary qubit in an optical cavity by controlling the non-inertial motion of a different probe atom. Furthermore, we show that by considering relativistic trajectories of the probe, we enhance the efficiency of the quantum control. We explore the possible use of these relativistic techniques to build universal quantum gates.
