No. 471600 Dilution Refrigerator for Superconducting Quantum Circuit Measurements

To all Potential/Interested Suppliers, Brookhaven Science Associates, LLC (herein known as “BSA”), operator of Brookhaven National Laboratory (BNL) under a Prime Contract with the U.S. Department of Energy (DOE), is seeking expressions of interest from firms regarding a dilution refrigerator for superconducting quantum circuit measurements as outlined in the following attachments:

Attachment A – Technical Specifications Dilution Refrigerator Attachment B – BNL-QA-101 Revision 04/2025

Please note that this is an RFI/Sources Sought notice, not a Request for Proposal, and no solicitation exists at this time.

This RFI is for informational and planning purposes only and is not to be construed as a commitment by the U.S. Government, nor will the U.S. Government pay for information received. The information from this notice will help the Department of Energy (DOE) Office of Basic Energy Sciences (BES) survey available resources.

Background:

The Co-design Center for Quantum Advantage (C2QA) at Brookhaven National Laboratory is planning to acquire a dilution refrigerator system for near-quantum-limited characterization of various quantum information circuits (“DRSQ”), including superconducting qubit and high-Q microwave resonators. The DRSQ should be a cryogen-free (“dry”) system and optimized for high-fidelity DC/RF measurements of superconducting circuits. It must enable integration of multiple RF (microwave and millimeter-wave) lines with cryogenic filtering and amplification, sufficient DC wiring for device control, and infrastructure to support near-quantum-limited readout.

This RFI describes specifications for a dilution refrigerator platform for high-fidelity DC/RF measurements of superconducting circuits at mK temperature. The system must include the following components: (1) A modular, cryogen-free dilution refrigerator that has base temperature < 10 mK and is capable of continuous operation at 20 mK (100 mK) with cooling power ≥ 16 μW (≥ 400 μW) at the mixing chamber (MXC); (2) a fully integrated, 2-stage pulse tube cryocooler that delivers a cooling power ≥ 2.35 W at 4.2 K; (3) a modular, automated gas handling system (GHS) that is capable of full system diagnostics; (4) modular wiring for DC and RF I/O signals to MXC; (5) various cryogenic electronics ready for quantum circuit measurements; and (6) computerized control hardware/software and thermometry interface. The vendor must provide onsite service that covers system installation, start-up, and training.

Please provide the following information:

1. Can you provide a tool with specifications meeting or exceeding the request in this document?

2. Can you provide a site preparation guide?

3. What are room requirements for the instrument (temperature control, electricity, vibrational etc.)?

4. What are the footprints of the proposed equipment?

5. What is the model of the compressor to be used for cryogen-free cooling? What is the operation voltage for the compressor?

6. Does the system allow low-temperature electronics be configured/replaced by customer?

7. Does the tool have electrical safety certification equivalent to UL/ETL/NRTL?

8. If certain requirements cannot be met, please indicate what can be achieved and demonstrated.

9. Would the system be manufactured in the United States? If not, what is the country of origin of the product?

10. What kind of warranty or servicing plan products do you offer?’

11. Could you please share a list of similar tools (no less than 10) that the vendor has installed in

US/Worldwide research institution/facilities (specified in the list).

We are open to all information you can and care to provide at this point. Please provide responses to BSA no later than November 25, 2025.
