Quantum Foundries

The Q-NEXT collaboration is launching two national quantum foundries to develop high-quality, standardized materials for quantum devices and systems. These resources will provide an in-demand source of materials and data to accelerate progress across the National Quantum Information Science Research Centers and in national QIS research.

Argonne Quantum Foundry

Located at Argonne National Laboratory, the Argonne Quantum Foundry is a 6,000-square-foot facility focused on developing scalable semiconductor quantum systems. The foundry will be home to a quantum computing test bed developed with insight from Intel. Other instruments to be co-located at the foundry are new diamond growth tools, environment-controlled annealing furnaces, tools to create qubits and materials transfer and flip-chip bonders for device integration.​

Spin qubit formation lab

Spin qubit formation lab

Dedicated area for annealing furnaces, synthesis and defect activation tools. Annealing capabilities include a rapid thermal annealer, an ampule annealing furnace, and a vacuum furnace for qubit activation.

Qubit synthesis and preparation lab

Qubit synthesis and preparation lab

Dedicated area for cutting and polishing diamond, silicon carbide and other solid-state systems, preparing them for growth synthesis and providing new avenues for device integration.

Surface treatment lab

Surface treatment lab

Area equipped with sample cleaning and dedicated pechloric-acid-based tri-acid cleaning protocol for surface preparation of diamond and other solid-state hosts.

Optical processing and characterization lab

Optical processing and characterization lab

Optics lab dedicated to ultrafast pulsed lasers for local qubit creation and annealing.

SLAC Detector Microfabrication Facility

The SLAC Detector Microfabrication Facility (DMF), located at SLAC National Accelerator Laboratory, is a 5,500-square-foot, class-100 cleanroom on the ground floor of the lab’s three-story Arrillaga Science Center. The facility, a superconducting quantum foundry, consists of a series of advanced equipment and metrology tools to support the state-of-the-art superconducting processes for a wide range of devices and sensors on 150-mm wafers. Facility capabilities include design, fabrication, and device characterization using cryogenic testing. The SLAC facility will establish methods and standards to improve the yield and robustness of superconducting processes to provide efficient, consistent, high-quality, and high-yield capabilities for superconducting quantum devices to support Q-NEXT and leverage other DOE missions.

Lithography bay cleanroom

Lithography bay cleanroom

This ISO 5 cleanroom in the lithography bay will contain an ASML stepper, a Heidelberg laser direct write system, tracks, wet benches and related metrology tools.

Main clean aisle

Main clean aisle

The main clean aisle connects six clean bays. Each bay accommodates a specific category of equipment and related metrology tools for device fabrication. Behind each door is a chase where supporting pumps, chillers and heat exchangers reside.
