First Measurement of Correlated Charge Noise in Superconducting Qubits at an Underground Facility
G. Bratrud, S. Lewis, K. Anyang +35
We measure space- and time-correlated charge jumps on a four-qubit device, operating 107 meters below the Earth's surface in a low-radiation, cryogenic facility designed for the ch…

Cryogenic optical beam steering for superconducting device calibration
K. Stifter, H. Magoon, A. J. Anderson +22
We have developed a calibration system based on a micro-electromechanical systems (MEMS) mirror that is capable of delivering an optical beam over a wavelength range of 180 -- 2000…
