STATEMENT OF WORK/REQUIREMENTS DOCUMENT

Title: ppKTP Purchase Request Requesting Lab: Physical Measurements Lab (PML), Applied Physics (AP), Magnetic Imaging Group (MIG)

I. BACKGROUND INFORMATION

This procurement request is for the purchase of six (6) periodically poled potassium titanyl phosphate (ppKTP) crystals with anti-reflection (AR) coatings at 1550 nm from Raicol Crystals Ltd. These crystals will be used in a heralded single-photon source for quantum optics experiments that require highly indistinguishable photons.

The ppKTP crystals will operate in a controlled laboratory environment and will be integrated into a nonlinear optical setup to generate photon pairs via spontaneous parametric down-conversion (SPDC). This purchase supports ongoing research in quantum information science, particularly in the development of sources for photonic quantum computing, quantum communication, and fundamental tests of quantum mechanics. The high indistinguishability of photons produced by these crystals is critical for quantum interference experiments and applications requiring entangled photon pairs.

This acquisition aligns with previous and ongoing procurements of quantum optics components and is part of a broader effort to enhance the lab’s capabilities in single-photon generation and manipulation.

Purpose/Objective: SPDC of 775nm light into indistinguishable single photons for quantum networking

Delivery shall be F.O.B Destination and shall occur in accordance with the delivery due dates provided in the above table.

FOB Destination means: The contractor shall pack and mark the shipment in conformance with carrier requirements, deliver the shipment in good order and condition to the point of delivery specified in the purchase order, be responsible for any loss of and/or damage to the goods occurring before receipt and acceptance of the shipment by the consignee at the delivery point specified in the purchase order; and pay all charges to the specified point of delivery. The contractor shall deliver all Line Items to:

National Institute of Standards and Technology Shipping and Receiving 325 Broadway, Building 1, Wing 5 Boulder, CO 80303 Michael Grayson

***Due to ongoing limited site access of the NIST facilities, the Awardee SHALL confirm with the Designated Government Official and the Contracting Officer prior to ANY shipment to NIST***

VIII. INSPECTION & ACCEPTANCE

In addition to the inspection and acceptance terms articulated in 52.212-4, the Government reserves the right to perform such performance tests and evaluations as defined below to verify specified system performance. Such tests and evaluations, if performed, shall be conducted within the environment that the system is to be operated. The Contractor has the right to be present during the tests and evaluations, if performed, at the Contractor’s expense.

Performance Tests:

1. List performance tests here

NIST may choose at its discretion to forego this part of acceptance testing.

A visual inspection of the equipment will be performed by the NIST TPOC to identify surface defects or any form of indication that any equipment was damaged during transport to NIST. The Government shall have sole discretion to require repair or replacement of damaged and/or nonconforming supplies at no cost to the Government. The Government at any time prior to acceptance shall reject the equipment due to defects and/or nonconformance. The vendor is responsible for latent defects discovered any time after final inspection. However, the extent of its liability shall be prorated over the useful life of the equipment.

Ownership of the equipment shall transfer to NIST upon acceptance by the Government.

The Government will test, inspect, and accept or reject the equipment within (insert working days it will take to inspect, accept or reject) of the receipt of the equipment unless otherwise indicated above. The Government reserves the right to conduct quality assurance testing to confirm that a given instrument(s) meets the manufacturer’s and/or the Government’s performance specifications. It is anticipated that the equipment will meet all manufacturer’s specifications and/or the Government’s performance specifications identified in the most recent operations and maintenance manual for each piece of equipment and/or in this document.

IX. WARRANTY

The contractor shall warranty the entire system for a period of a minimum of (enter required warranty term) after receipt of the equipment and shall be in accordance with terms in FAR 52.212-4. Warranty shall commence upon acceptance of the system by the Government and at a minimum shall include the following:

X. PAYMENT SCHEDULE (This section to be revised as needed) Advance payment is not authorized. The Contractor must invoice in arrears according to the payment schedule.

The Contractor shall be paid, in accordance with Net 30-day payment terms, upon receipt and acceptance of a proper invoice, in accordance with the following schedule:
