Short summary
Electron spin detection was recently demonstrated using superconducting circuits and amplifiers at millikelvin temperatures, reaching the quantum limit of sensitivity. We use such a setup to measure electron-spin-echo envelope modulation on a small number of electron spins, in two model systems: bismuth donors in silicon and erbium ions doped in CaWO4 (calcium tungstate). Our results are a proof of principle that hyperfine spectroscopy is feasible with these quantum-limited ESR spectrometers.
