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…

Individual solid-state nuclear spin qubits with coherence exceeding seconds
James O'Sullivan, Jaime Travesedo, Louis Pallegoix +14
The ability to coherently control and read out qubits with long coherence times in a scalable system is a crucial requirement for any quantum processor. Nuclear spins in the solid…
