On-demand quantum state transfer and entanglement between remote microwave cavity memories

Summary

Demonstrates deterministic quantum state transfer and entanglement between two remote superconducting cavity quantum memories using shaped microwave photons. Average transfer fidelity of 76%, improved to 87% with error heralding (success probability 0.87). Uses parametrically controlled emission and absorption of microwave photons via transmon intermediaries. Demonstrated in both single- and multi-photon encodings.
