Protecting backaction-evading measurements from parametric instability
E. P. Ruddy, Y. Jiang, N. E. Frattini +2
Noiseless measurement of a single quadrature in systems of parametrically coupled oscillators is theoretically possible by pumping at the sum and difference frequencies of the two…
Integrating planar circuits with superconducting 3D microwave cavities using tunable low-loss couplers
Ziyi Zhao, Eva Gurra, Eric I. Rosenthal +3
We design and test a low-loss interface between superconducting 3-dimensional microwave cavities and 2-dimensional circuits, where the coupling rate is highly tunable. This interfa…
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…
Optically Distributing Remote Two-node Microwave Entanglement using Doubly Parametric Quantum Transducers
Akira Kyle, Curtis L. Rau, William D. Warfield +4
Doubly-parametric quantum transducers (DPTs), such as electro-opto-mechanical devices, show promise as quantum interconnects between the optical and microwave domains, thereby enab…
Minimally-diffracting quartz for ultra-low temperature surface acoustic wave resonators
Alec L. Emser, Brendon C. Rose, Lucas R. Sletten +2
We simulate and experimentally demonstrate the existence of an orientation of quartz which minimizes diffraction losses in surface acoustic wave (SAW) resonators at ultra-low tempe…
