Raman Transitions between two Superconducting Cavity Modules via Parametric Conversion: Part I

ORAL

Abstract

We investigate a simple quantum network capable of state transfer and entanglement between superconducting 3D cavities in two spatially separated modules. Bidirectional communication between the cavity modes is established by coupling each cavity to the same standing-wave mode of a superconducting coaxial cable via parametric conversion. The system can be made robust to loss in the cable by using off-resonant conversion to engineer a virtual Raman transition between the three modes (cavity-cable-cavity), which suppresses the population of the lossy cable mode. Preliminary experimental results regarding state transfer will be discussed.
