Optomechanical interface between telecom photons and spin quantum memory

Quantum networks enable a broad range of practical and fundamental applications spanning from distributed quantum computing to sensing and metrology. A cornerstone of such networks is an interface between telecom photons and quantum memories, which has proven challenging for the case of spin-mechanical memories. Here we demonstrate a novel approach based on cavity optomechanics that utilizes the susceptibility of spin qubits to strain. We use it...
