SRF technology

One of the most difficult problems to overcome in developing a quantum computer is finding a way to maintain the lifespan of information held in quantum bits, called qubits. Researchers at Fermilab and Argonne National Laboratory are working to determine whether devices used in particle accelerators can help solve the problem. The team will run simulations on high-performance computers that will enable them to predict the lifespan of information held within these qubits using smaller versions of these devices, taking us one step closer to the age of quantum computing.

From Northwestern University, Nov. 8, 2019: Northwestern and Fermilab researchers, including Fermilab scientists Anna Grassellino and Alexander Romanenko, show how impurities can increase the maximum accelerating field of superconducting radio-frequency cavities, a finding with huge potential cost advantages.

Fermilab’s quantum program includes a number of leading-edge research initiatives that build on the lab’s unique capabilities as the U.S. center for high-energy physics and a leader in quantum physics research. On the tour, researchers discussed quantum technologies for communication, high-energy physics experiments, algorithms and theory, and superconducting qubits hosted in superconducting radio-frequency cavities.

From Forbes, Jan. 24, 2018: Fermilab will provide half of SLAC’s LCLS-II cryomodules, and Jefferson Lab in Newport News, Virginia, will provide the other half. Fermilab is located in Illinois, so the very first cryomodule that arrived at SLAC by truck last week made a hefty trip from Illinois to California – essentially making a trip across the whole of the U.S.
