Non-Gaussian-to-Gaussian state transformation for distributed quantum computing.

Quantum state transformation of qubit states from a superconducting quantum processor into CV propagating microwaves is explored. We focus on reversible, efficient non-Gaussian-to-Gaussian transducing processes, taking advantage of communication protocols though noisy channels. As an alternative, we consider block-chain-type protocols, which distribute the information over several channels less sensitive to decoherence.
