Precision hyperfine spectroscopy of an individual nuclear-spin-9/2
J. Travesedo, Z. W. Huang, L. Mykolyshyn +12
Single-spin magnetic resonance spectroscopy promises to yield structural and chemical information at the level of individual atoms or molecules, in a non-invasive way. Here, we use…

Enhancing the sensitivity of single microwave photon detection with bandwidth tunability
Louis Pallegoix, Jaime Travesedo, Alexandre S. May +4
We report on the characteristics of a microwave photon counter device based on a superconducting transmon qubit. Its design is similar to [arXiv:2307.03614], with an additional ban…

Noise Mitigation in Single Microwave Photon Counting by Cascaded Quantum Measurements
Alexandre S. May, Leo Sutevski, Jeanne Solard +7
While single-photon counting is routinely achieved in the optical domain, operational single microwave photon detectors (SMPDs) have only recently been demonstrated. SMPDs are crit…
