Simulating moving cavities in superconducting circuits

Journal article, 2019

We theoretically investigate the simulation of moving cavities in a superconducting circuit setup. In particular, we consider a recently proposed experimental scenario where the phase of the cavity field is used as a moving clock. By computing the error made when simulating the cavity trajectory with superconducting quantum interference devices (SQUIDs), we identify parameter regimes where the correspondence holds, and where time dilation and corrections due to clock size and to particle creation coefficients are observable. These findings may serve as a guideline when performing experiments on simulation of moving cavities in superconducting circuits.
