PRESS RELEASE — Quantum computing digital chip company SEEQC has been selected by the Department of Energy to design and produce superconducting quantum interference devices (SQUIDs). SQUIDs are extremely sensitive magnetometers used to measure incredibly subtle signals for many applications including for dark matter detection, sensor readout, qubit readout in quantum computing, and medical imaging.
The $200,000 Small Business Innovative Research grant will fund the project, Development of SQUID amplifier for readout electronics of Transition Edge Sensors, to advance superconducting readout capabilities. The project’s primary objective is to manufacture an ultra-sensitive SQUID amplifier that operates with low power and low noise for fundamental science research in dark matter, neutrino science and cosmology.
While dark matter comprises around 27% of the universe’s total mass-energy, its nature remains unknown. For now, dark matter’s existence is inferred only through its gravitational effects. Continuous improvements in detector technologies – including SEEQC’s more advanced SQUID – and new theoretical insights may eventually lead to a confirmed direct detection.
Aritoki Suzuki, Physicist Staff Scientist at Lawrence Berkeley National Laboratory (LBNL), expressed excitement about collaborating with SEEQC on this transformative project, stating, “The development of an improved SQUID amplifier will have far-reaching implications for research related to Dark Matter, the early universe, and matter-antimatter asymmetry.”
The development and production of SEEQC’s new SQUID will solve some existing problems with the technology. Lower power dissipation will allow the SQUID to be integrated with more sensitive sensors operating at ultra cold temperatures, while lower noise also improves sensitivity. SEEQC’s production will improve the availability and accessibility of these innovative devices for the scientific community. It also has a commercial use: superconducting amplifiers and Josephson Junction technology plays an important role in quantum computing, microscopy, and security.
Detecting cosmic microwave background (CMB) radiation
SEEQC is actively working with LBNL on the CMB-S4 project. CMB-S4 is the next-generation ground-based CMB experiment with a goal of transformative discoveries in fundamental physics, cosmology, astrophysics, and astronomy, helping us to understand the beginning, history, and makeup of the universe. The experiment will survey the sky with 496,000 cryogenically cooled superconducting detectors with 21 telescopes at the South Pole and in the Chilean Atacama Desert for 7 years. More than 500 horn coupled Transition Edge Sensor detector array modules are planned for deployment at both experiment sites.
Beyond advancing fundamental physics research, SEEQC’s SQUIDs have diverse applications spanning quantum technologies and medical imaging.
Energy-efficient circuits for quantum information systems
Daniel Yohannes, Principal Investigator of the project and Director of Fabrication at SEEQC, elaborates, “Various elements of the project, including superconducting circuitry, Josephson junctions, and cryogenics, are pivotal technologies for the quantum computing and quantum sensing domains.”
Compact, low-cost medical imaging
