TLS loss in superconducting resonators on epitaxial hBN thin films
J. Christiansen-Salameh, D. J. Temples, R. Linehan +21
The integration of low-loss dielectrics into superconducting circuits is of importance to the functionality of quantum computers and sensors. In this work, we fabricate and measure…
Real-Time Detection of Charge Jumps in Superconducting Qubits with a Convolutional Neural Network
Daniel Gaytan-Villarreal, Peter Meiring, Daniel Baxter +6
Ionizing radiation from cosmic rays and gammas can induce discontinuous jumps in the environmental charge of superconducting qubits (charge jumps), causing correlated errors that c…
End-to-end workflow for machine learning-based qubit readout with QICK and hls4ml
Giuseppe Di Guglielmo, Botao Du, Javier Campos +10
We present an end-to-end workflow for superconducting qubit readout that embeds co-designed Neural Networks (NNs) into the Quantum Instrumentation Control Kit (QICK). Capitalizing…
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…
Estimating the Energy Threshold of Phonon-mediated Superconducting Qubit Detectors Operated in an Energy-Relaxation Sensing Scheme
R. Linehan, I. Hernandez, D. J. Temples +13
In recent years, the lack of a conclusive detection of WIMP dark matter at the 10 GeV/c mass scale and above has encouraged development of low-threshold detector technology a…
Performance of a Kinetic Inductance Phonon-Mediated Detector at the NEXUS Cryogenic Facility
Dylan J Temples, Osmond Wen, Karthik Ramanathan +18
Microcalorimeters that leverage microwave kinetic inductance detectors to read out phonon signals in the particle-absorbing target, referred to as kinetic inductance phonon-mediate…
