Characterization of NbTiN films with thicknesses below 20 nm for low power kinetic inductance amplifiers
A. Giachero, M. R. Vissers, J. D. Wheeler +6
A quantum-limited amplification chain is a fundamental advantage for any application that may benefit from the detection of very faint signals. Reading out arrays of superconductin…
Improved microwave SQUID multiplexer readout using a kinetic-inductance traveling-wave parametric amplifier
M. Malnou, J. A. B. Mates, M. R. Vissers +5
We report on the use of a kinetic-inductance traveling-wave parametric amplifier (KITWPA) as the first amplifier in the readout chain of a microwave superconducting quantum interfe…
New Results from HAYSTAC's Phase II Operation with a Squeezed State Receiver
HAYSTAC Collaboration, M. J. Jewell, A. F. Leder +26
A search for dark matter axions with masses has been performed using the HAYSTAC experiment's squeezed state receiver to achieve sub-quantum limited noise. This rep…
Bandwidth and visibility improvement in detection of a weak signal using mode entanglement and swapping
Yue Jiang, Elizabeth P. Ruddy, Kyle O. Quinlan +3
Quantum fluctuations constitute the primary noise barrier limiting cavity-based axion dark matter searches. In an experiment designed to mimic a real axion search, we employ a quan…
Performance of a Kinetic-Inductance Traveling-Wave Parametric Amplifier at 4 Kelvin: Toward an Alternative to Semiconductor Amplifiers
M. Malnou, J. Aumentado, M. R. Vissers +4
Most microwave readout architectures in quantum computing or sensing rely on a semiconductor amplifier at 4 K, typically a high-electron mobility transistor (HEMT). Despite its rem…
A quantum-enhanced search for dark matter axions
K. M. Backes, D. A. Palken, S. Al Kenany +21
In dark matter axion searches, quantum uncertainty manifests as a fundamental noise source, limiting the measurement of the quadrature observables used for detection. We use vacuum…
