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…
A cavity entanglement and state swapping method to accelerate the search for axion dark matter
K. Wurtz, B. M. Brubaker, Y. Jiang +3
In cavity-based axion dark matter detectors, quantum noise remains a primary barrier to achieving the scan rate necessary for a comprehensive search of axion parameter space. Here…
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…
Efficient and Low-Backaction Quantum Measurement Using a Chip-Scale Detector
Eric I. Rosenthal, Christian M. F. Schneider, Maxime Malnou +13
Superconducting qubits are a leading platform for scalable quantum computing and quantum error correction. One feature of this platform is the ability to perform projective measure…
Experimental constraint on axion-like particle coupling over seven orders of magnitude in mass
Tanya S. Roussy, Daniel A. Palken, William B. Cairncross +11
We use our recent electric dipole moment (EDM) measurement data to constrain the possibility that the HfF EDM oscillates in time due to interactions with candidate dark matter…
An improved analysis framework for axion dark matter searches
D. A. Palken, B. M. Brubaker, M. Malnou +17
In experiments searching for axionic dark matter, the use of the standard threshold-based data analysis discards valuable information. We present a Bayesian analysis framework that…
Squeezed vacuum used to accelerate the search for a weak classical signal
M. Malnou, D. A. Palken, B. M. Brubaker +3
Many experiments that interrogate fundamental theories require detectors whose sensitivities are limited by the laws of quantum mechanics. In cavity-based searches for axionic dark…
Results from phase 1 of the HAYSTAC microwave cavity axion experiment
L. Zhong, S. Al Kenany, K. M. Backes +18
We report on the results from a search for dark matter axions with the HAYSTAC experiment using a microwave cavity detector at frequencies between 5.6-5.8. We exclude a…
Optimal operation of a Josephson parametric amplifier for vacuum squeezing
M. Malnou, D. A. Palken, Leila R. Vale +2
A Josephson parametric amplifier (JPA) can create squeezed states of microwave light, lowering the noise associated with certain quantum measurements. We experimentally study how t…
Design and Operational Experience of a Microwave Cavity Axion Detector for the 20-100 micro-eV Range
S. Al Kenany, M. A. Anil, K. M. Backes +17
We describe a dark matter axion detector designed, constructed, and operated both as an innovation platform for new cavity and amplifier technologies and as a data pathfinder in th…
First results from a microwave cavity axion search at 24 micro-eV
B. M. Brubaker, L. Zhong, Y. V. Gurevich +17
We report on the first results from a new microwave cavity search for dark matter axions with masses above . We exclude axion models with two-photon coupling $g_{aγγ…
