We introduce an optically pumped, superconducting, electrooptic device that exhibits strong interactions between microwave and telecom wavelength light. We demonstrate ultra-low noise wavelength conversion, dynamical backaction, and deterministic electro-optic entanglement generation. More recently we also used it to demonstrate all-optical, single-shot qubit readout without the need for any cryogenic microwave components. Such microwave photonic interconnects that operate close to the quantum limit offer new perspectives for a number of scaling, networking and sensing applications.
