SQMS flagship facilities

Seen in QCL-1 at Fermilab is dilution refrigerator #2 at the forefront. A table with a nine-cell SRF cavity with dilution refrigerator #1 are in the background.

Fermilab Quantum Computing Lab One (QCL-1)

QCL-1 was developed under the leadership of PI Alexander Romanenko. Two state-of-the-art, extra-large dilution fridges serve as quantum testbeds with multi-qubit control capabilities for quantum computing, sensing and communication research. To allow researchers to perform multiple experiments in a single cooldown, each dilution refrigerator can hold multiple SRF cavities and qubit chips. The large refrigerators have the capacity for meter-long cavities with many cells for multimode operation. One fridge is designed to sustain larger heat loads at the two-kelvin stage for special quantum-sensing physics experiments, such as searches for dark matter.

Fermilab Quantum Computing Lab Two (QCL-2)

QCL-2 is a high-flexibility nanofabrication facility to advance cutting-edge research in high-quality films and materials for next-generation superconducting qubits. Here, researchers will focus on superconducting films and quantum devices with capabilities beyond current state-of-the-art facilities. QCL-2 will offer high-quality film deposition tools, double-angle evaporation tools, imaging and characterization tools, wet-processing benches, and post-processing and packaging tools.

Fermilab Quantum Computing Lab Three (QCL-3)

SQMS is converting a garage on Fermilab’s campus into a world-class quantum testbeds lab that will enable researchers to expand QIS experimentation into previously unexplored territory. QCL-3 will be home to six new extra-large dilution refrigerators and devices capable of generating millikelvin temperatures and extremely high and low magnetic field environments. Here, SQMS researchers will use unique cavities, quantum computing chips and sophisticated equipment with advanced frequency-control tools and parts-per-billion precision to perform cutting-edge experiments.

Colossus

Colossus will be the world’s largest cooling dilution refrigerator. Housed within the Heavy Assembly Building on Fermilab’s campus, Colossus will contain hundreds to thousands of cavities with varying geometries and will have a cold volume of five cubic meters. This volume is significantly larger than the dilution refrigerators that are currently used for research and development and will have 10 times the cooling capacity. Originally used to test the solenoids for Fermilab’s upcoming Mu2e experiment, the tank for the dilution refrigerator has tested components at four kelvin and is now being upgraded to hold components at 10 millikelvin.

    SRF cavities for accelerator applications are typically heated at temperatures ranging from 120 to 900 Celsius. Fermilab’s heat treatment facilities include high-temperature, high-vacuum furnaces for degassing hydrogen from cavities and implanting nitrogen. The low-temperature heat treatment facilities were recently reconfigured to heat treat cavities at temperatures in the 300 to 400 Celsius range. This treatment is crucial for breaking up oxide and dissolving it into the niobium surface to remove it and substantially reduce TLS losses. This treatment was shown to increase quality factors in cavities at low temperatures and low fields from the 109 range to the 1010 range.
  • SRF cavity-coating facilities
    Niobium has become an extremely high-performing SRF material after decades of development, but there are other promising SRF materials in the early stages of development that could offer potential performance improvements, even compared to niobium. Fermilab has two current early-career award recipients performing research on niobium-tin, and Fermilab’s coating facilities produce world-leading niobium-tin cavities. A new furnace to be delivered in 2023 will be capable of performing atomic layer deposition (ALD) and chemical vapor deposition (CVD) for novel materials and layered structures.

Research Computing is home to the UA Laboratory for Immersive Visualization Environments (AZ-LIVE). AZ-LIVE is a space where university researchers, faculty and students are immersed in interactive, 3-D, stereo, computer-generated worlds. The combination of 3-D computer graphics, stereoscopic projection technology, acoustical tracking devices and four-channel audio creates the illusion of being present in a virtual world. The environment utilizes a multi-processor HPC workstation cluster capable of handling and displaying large datasets. The advanced projection and tracking system, along with the computing technology in AZ-L IVE, combine to create an environment in which a wide range of applications, models and virtual worlds can be displayed and navigated interactively.
