"Localized relativistic quantum systems for quantum information processing":
The quantum era has started. Quantum Information has greatly developed in the past decades and has reached the stage where commercial applications become available. Although cutting edge experiments might operate at regimes where relativistic effects play a role, it is still unclear how such effects enter standard quantum information tasks and if they can be exploited at all.
We present a new approach to understanding the effects of Relativity on Quantum Information tasks which has been developed within the novel and exciting field of Relativistic Quantum Information. We investigate the effects of relativistic motion of a cavity that contains a quantum field. We are able to show that while particles are excited due to motion, entanglement can also be generated. Furthermore, we demonstrate that trajectories can always be tailored to obtain single and two mode gates such as beam splitter and two mode squeezer. Such gates are at the core of universal quantum computation with continuous variables. Finally, we apply our framework to generate square cluster states within single moving cavities. These states are a resource for universal quantum computation with continuous variables. The predictions of our work can be investigated with current technology within superconducting circuits. Our results are being currently tested in the laboratory
