Abstract

Quantum technologies are widely expected to bring about many key technological advances this century. Quantum metrology and quantum information have been so far successfully applied in the design of devices that outperform their classical counterparts by exploiting quantum properties. Impressively, the quantum era is now reaching relativistic regimes. Table-top experiments demonstrate relativistic effects in quantum fields and long range quantum experiments will soon reach regimes where relativity kicks in. The general expectation is that relativity will produce small effects in such technologies.

In this talk I will show how relativistic effects can be used to improve quantum measurement technologies and implement universal quantum computation. Experiments are currently taking place to demonstrate our results in superconducting circuits. I will also show that the twin paradox can be demonstrated in this experimental setup. Our analysis predicts that the spatial extension of clocks and the dynamical Casimir effect make moving clocks tick slower.
