A number of current approaches to quantum and neuromorphic computing usesuperconductors as the basis of their platform or as a measurement component,and will need to operate at cryogenic temperatures. Semiconductor systems aretypically proposed as a top-level control in these architectures, withlow-temperature passive components and intermediary superconducting electronicsacting as the direct interface to the lowest-temperature stages. Thearchitectures, therefore, require a low-power superconductor-semiconductorinterface, which is not currently available. Here we report a superconductingswitch that is capable of translating low-voltage superconducting inputsdirectly into semiconductor-compatible (above 1,000 mV) outputs at kelvin-scaletemperatures (1 K or 4 K). To illustrate the capabilities in interfacingsuperconductors and semiconductors, we use it to drive a light-emitting diode(LED) in a photonic integrated circuit, generating photons at 1 K from alow-voltage input and detecting them with an on-chip superconductingsingle-photon detector. We also characterize our device's timing response (lessthan 300 ps turn-on, 15 ns turn-off), output impedance (greater than 1M{\Omega}), and energy requirements (0.18 fJ/um^2, 3.24 mV/nW).
