Optically-Heralded Entanglement of Superconducting Systems in Quantum Networks
Invention type: Technology
/
Case number: #22977
The typical approach to transfer quantum information between two superconducting quantum computers is direct microwave-to-optical and optical-to-microwave transduction, which has low fidelity due to the low microwave-optical coupling rates and added noise. We break this rate-fidelity trade-off by end-to-end entanglement with one detected photon and teleportation, unifying and simplifying entanglement generation between devices in quantum networks
