Quantum information processing in spacetime
Cutting-edge experiments in quantum information have reached regimes where relativistic effects can no longer be neglected. Therefore, it is timely to understand what are the effects of relativistic motion on entanglement and other quantum properties. In this talk we will show how entanglement is generated between the modes of a cavity undergoing non-uniform motion. Via the equivalence principle, our results suggest that gravity can effect entanglement. Moreover, the relativistic motion of quantum systems can be used to perform quantum gates. These predictions can be tested in circuit QED where it is possible to simulate quantum fields undergoing relativistic motion.
