Quantum photonic processing via electro-optic components typically requires electronic links across different operation environments, especially when interfacing cryogenic such as superconducting single photon detectors with room-temperature control and readout electronics. However, driving electronics can introduce detrimental parasitic effects. Here we show an all-optical of a nanowire detector (SNSPD), completely electrically decoupled from room temperature We provide the power for photodiode, detection signals modulator in same cryostat. This method opens possibility circuits, feedforward quantum computing.
