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…

Superconducting Parallel-Plate Resonators for the Detection of Single Electron Spins

André Pscherer, Jannes Liersch, Patrick Abgrall +7

We introduce a multilayer superconducting microwave resonator with sub-Ohm impedance optimized for high coupling strength to single electron spins. The design minimizes the magneti…

Engineering protected cavity-QED interactions through pulsed dynamical decoupling

I. Arrazola, P. Bertet, Y. Chu +1

We study a generic cavity QED setup under conditions where the coupling between the two-level systems and a single bosonic mode is significantly degraded by low-frequency noise. To…

Addressing spins at the clock transitions with a frequency- and bandwidth-tunable superconducting resonator

Yutian Wen, V. Ranjan, T. Lorriaux +5

Solid-state spin ensembles addressed via superconducting circuits are promising candidates for quantum memory applications, offering multimodal storage capability and second-long c…

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…
