Quantum Network pluggable 4-channel superconducting nanowire single-photon detector (SNSPD) system

The National Institute of Standards and Technology (NIST) is conducting market research to identify potential sources that can provide a Quantum Network pluggable 4-channel superconducting nanowire single-photon detector (SNSPD) system. The system should meet specific technical specifications, including detection efficiency, power requirements, and operating conditions. The system will be used for quantum network metrology and should be able to operate continuously. The contractor shall provide a warranty for the system for 12 months after delivery. * The system must have four SNSPDs with detection efficiency of >80% for wavelengths between 1300 nm and 1600 nm. * The system must operate at 110V/15A without water cooling. * The system must be able to operate continuously (24/7). * The fiber connection to the system must be SMF28 with E2000 bulk-head connector. * The system must be able to be operated through the quantum network from a remote client. * The contractor must provide a command library to fully control the system using python.
