Quantum Research Bits: Is silicon the ideal substrate for qubits? It depends who you ask.

    From Semiconducting Engineering, September 12, 2022: How do you extend the lifespan of qubits? Researchers at the Supercomputing Quantum Materials and Systems Center say silicon limits the lifespan of qubits because of quantum decoherence. Fermilab’s Alexander Romanenko discusses recently published research on how individual sub-components contribute to the decoherence of the qubits. Could sapphire be a better choice for future quantum chips?

    Improving quantum computer performance with new control electronics

      From Electronic Specifier, September 2, 2022: Electronic Specifier’s podcast talks with Gustavo Cancelo, Lead Engineer at Fermilab about a project that is developing new control electronics for quantum computers known as QICK. Developed by a team of engineers at Fermilab in collaboration with the University of Chicago, the Quantum Instrumentation Control Kit provides computing experiments with a new control and readout electronics option that will significantly improve performance while replacing cumbersome and expensive systems.

      Helium’s chilling journey to cool a particle accelerator

        From SLAC, August 31, 2022: Fermilab researchers worked with a team of 20 operators and engineers at SLAC on cryogenics to build a helium-refrigeration plant to lower the LCLS-II accelerator to superconducting temperatures. Now, it only takes one and a half hours to make a superconducting particle accelerator at SLAC colder than outer space.
