Quantum Detector System

The National Institute of Standards and Technology (NIST) seeks to procure a 2-Channel Superconducting Nanowire Single Photon Detector (SNSPD) System for its Quantum Optical Networking program within the Smart Connected Systems Division. The system must meet stringent technical specifications including greater than 70% detection efficiency for wavelengths between 1300-1600 nm, capability of 10^7 counts per second, and 24/7 operation at 110V/15A without water cooling requirements. The detector system must be remotely operable through a quantum network, include a Python command library, and be rack-mountable to support quantum networking research focused on entanglement distribution and stability experiments. Evaluation will be based on two primary factors: technical capability and price, with the government seeking the technically acceptable, lowest-priced offer that meets all specifications. Electronic quotes must be submitted in two volumes (technical and price) to Jennifer Lohmeier by 10:00 AM ET on July 3, 2025, with quotes remaining valid for 90 calendar days.

This procurement operates without any set-aside designation and is unrestricted to all qualified offerors registered in the System for Award Management (SAM). The solicitation seeks one detector system with delivery required within two weeks after receipt of order, specifically by August 22, 2025. The equipment will be delivered to NIST's Gaithersburg, Maryland campus and initially deployed in Buildings 222 and 220 for quantum networking experiments involving longer-distance transmission of entangled photons. The procurement falls under NAICS Code 334516 (Analytical Laboratory Instrument Manufacturing) with a small business size standard of 1,000 employees, and the government intends to award a firm fixed price purchase order. Payment is contingent upon successful installation, acceptance, and demonstration of all technical requirements, with warranty provisions included for parts, labor, and returns.
