This is a Requirements/Specification Document from the National Institute of Standards and Technology (NIST) for the procurement of a Polarization-Entangled Photon Source.

The document is issued by NIST's Communications Technology Laboratory, Quantum Communications Division, Quantum Network Architecture and Protocols Group (676.02). The acquisition seeks to procure one polarization-entangled photon source based on spontaneous parametric down-conversion (SPDC) technology. The system must be built using a periodically poled lithium niobate (PPLN) waveguide, capable of accepting an external pump laser and generating high-quality polarization-entangled photon pairs with temperature-tuning capabilities for phase-matching optimization.

Key technical specifications for the source include: turntable alignment-free design; photon pair wavelength centered at 1550 nm with 3 nm bandwidth; noise suppression greater than 75 dB; fidelity exceeding 98 percent; pair generation rate above 2 MHz; two-photon interference visibility greater than 98 percent; type-2 nonlinear process; fiber-coupled and FC/APC connector terminated input/output; external temperature controller capability; external pump laser acceptance; and continuous 24/7 operation design. Delivery is required to the NIST-Gaithersburg Mail Stop 676.02 facility in Gaithersburg, Maryland 20899 with completion within 16 weeks after receipt of order. The system requires direct delivery to the OU Building with acceptance expected within 7 business days. Installation includes turnkey installation services coordinated by the System/Materials Engineer (SME). Power requirements specify 120V single-phase at 10A maximum, 60 Hz frequency with standard NEMA L5-20P plug type in a common lab/office environment. Warranty includes a 1-year base manufacturer warranty covering labor, parts, and cost/liability for returns. Inspection and acceptance testing will be conducted by the POC with setup and system testing.
