Pitch & Catch II: Error-Correctable Multi-Photon State Transfer

ORAL

Abstract

Direct quantum state transfer suffers from photon loss in the transmission channel. Parametric conversion between microwave cavity memories and propagating photons allows for the deterministic transmission of multi-photon quantum states. These states can be made robust to photon loss. We encode a qubit within a subspace of definite parity—an error-correctable encoding—and transfer the state between memories. We measure the transfer efficiency to be at a level where parity measurement and feedback would improve the average state fidelity. With modest technical improvements, we expect to reach a regime where this error detection and correction yields a fidelity exceeding that already achieved for a single-photon encoding.
