摘要
Interfacing or entanglement between spatially separated quantum systems,such as superconducting qubits,semiconductor quantum dots,atomic qubits,and solid-state color centers,is crucial in quantum networks and distributed quantum computation[1].Significant progress has been made in generating entanglement between spatially separated quantum systems via optical links[2],while remote superconducting chips,whose quantum states are easily spoiled by optical photons,have been entangled via cryogenic microwave links[3].
