High-Throughput Microwave Package for Precise Superconducting Device Measurement
Wei-Ren Syong, Allie Miller, Emma Davis +6
Cryogenic microwave measurement of superconducting quantum devices is complicated by the packaging required to connect devices to control and readout circuitry. In this work, we ou…
Comparison of Nb and Ta Pentoxide Loss Tangents for Superconducting Quantum Devices
D. P. Goronzy, W. W. Mah, P. G. Lim +14
Superconducting transmon qubits are commonly made with thin-film Nb wiring, but recent studies have shown increased performance with Ta wiring. In this work, we compare the resonat…
Lithographic integration of TES microcalorimeters with SQUID multiplexer circuits for large format spectrometers
Robinjeet Singh, Avirup Roy, Daniel Becker +12
Arrays of hundreds or thousands of low temperature detectors have been deployed for many experiments, both bolometers for long wavelength applications and calorimeters for shorter…
Kinetic Inductance Traveling Wave Parametric Amplifiers Near the Quantum Limit: Methodology and Characterization
L. Howe, A. Giachero, M. Vissers +7
We present a detailed simulation and design framework for realizing traveling wave parametric amplifiers (TWPAs) using the nonlinear kinetic inductance of disordered superconductor…
Demonstration of a 1820 channel multiplexer for transition-edge sensor bolometers
J. C. Groh, Z. Ahmed, J. Austermann +16
The scalability of most transition-edge sensor arrays is limited by the multiplexing technology which combines their signals over a reduced number of wires and amplifiers. In this…
Noise limits for dc SQUID readout of high- resonators below 300 MHz
V. Ankel, C. Bartram, J. Begin +38
We present the limits on noise for the readout of cryogenic high- resonators using dc Superconducting Quantum Interference Devices (SQUIDs) below 300 MHz. This analysis uses rea…
Compact Superconducting Kinetic Inductance Traveling Wave Parametric Amplifiers with On-chip rf Components
Logan Howe, Andrea Giachero, Michael Vissers +4
Quantum computing systems and fundamental physics experiments using superconducting technologies frequently require signal amplification chains operating near the quantum limit of…
Measurable Improvement in Multi-Qubit Readout Using a Kinetic Inductance Traveling Wave Parametric Amplifier
M. A. Castellanos-Beltran, L. Howe, A. Giachero +4
Increasing the size and complexity of quantum information systems requires highly-multiplexed readout architectures, as well as amplifier chains operating near the quantum limit (Q…
