摘要：

Current microwave quantum technologies rely on quantum control and readout of microwaves in the electrical domain. The scaling of the superconducting quantum processors poses a major challenge due to the substantial heat load and limited space in the millikelvin environment. In this talk, I will give an overview of the status of superconducting quantum interconnects and discuss the field of quantum electro-optics. This includes, 1) Coherent control of a superconducting microwave cavity using laser light via electro-optical dynamical back-action; 2) Quantum-enabled microwave-optical transduction, ready for near-term heralded quantum network protocols; 3) Deterministic microwave-optical entanglement, useful for long-distance quantum communications and sensing applications. These results offer a viable route towards optical quantum networks of superconducting quantum processors.
