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…
Quantum metrology of low frequency electromagnetic modes with frequency upconverters
Stephen E. Kuenstner, Elizabeth C. van Assendelft, Saptarshi Chaudhuri +11
We present the RF Quantum Upconverter (RQU) and describe its application to quantum metrology of electromagnetic modes between dc and the Very High Frequency band (VHF) (…
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…
