• Abstract summary: Cryogenic opto-electronic interconnects are gaining increasing interest as a means to control and read out cryogenic electronic components. We demonstrate the opto-electronic bias and readout of a commercial four-pixel superconducting nanowire single-photon detector array. This demonstrates the potential of high-bandwidth, low noise, and low heat load opto-electronic interconnects for scalable cryogenic signal processing and transmission.

• Abstract: Cryogenic opto-electronic interconnects are gaining increasing interest as a means to control and read out cryogenic electronic components. The challenge is to achieve sufficient signal integrity with low heat load processing. In this context, we demonstrate the opto-electronic bias and readout of a commercial four-pixel superconducting nanowire single-photon detector array using a cryogenic photodiode and laser. We show that this approach has a similar system detection efficiency to a conventional bias. Furthermore, multi-pixel detection events are faithfully converted between the optical and electrical domain, which allows reliable extraction of amplitude multiplexed photon statistics. Our device has a passive heat dissipation of 2.6mW, maintains the signal rise time of 3ns, and operates in free-running (self-resetting) mode at a repetition rate of 600kHz. This demonstrates the potential of high-bandwidth, low noise, and low heat load opto-electronic interconnects for scalable cryogenic signal processing and transmission.

  Photonic addressing of superconducting circuits has been proposed to overcome wiring complexity and heat load challenges. Superconducting-photonic links suffer from an efficiency-noise trade-off that limits scalability. We analyze this trade-off and find the infidelity of qubit gates driven by photonic signals scales inversely with the number of photons used.
