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…
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…
Widely tunable on-chip microwave circulator for superconducting quantum circuits
Benjamin J. Chapman, Eric I. Rosenthal, Joseph Kerckhoff +6
We report on the design and performance of an on-chip microwave circulator with a widely (GHz) tunable operation frequency. Non-reciprocity is created with a combination of frequen…
Generating and verifying entangled itinerant microwave fields with efficient and independent measurements
H. S. Ku, W. F. Kindel, F. Mallet +5
By combining a squeezed propagating microwave field and an unsqueezed vacuum field on a hybrid (microwave beam-splitter), we generate entanglement between the two output modes. We…
