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…
Incoherent Measurement of Sub-10 kHz Optical Linewidths
Félix Montjovet-Basset, Jayash Panigrahi, Diana Serrano +5
Quantum state lifetimes , or equivalently homogeneous linewidths , are a key parameter for understanding decoherence processes in quantum systems and assessing t…
All-microwave spectroscopy and polarization of individual nuclear spins in a solid
J. Travesedo, J. O'Sullivan, L. Pallegoix +10
We report magnetic resonance spectroscopy measurements of individual nuclear spins in a crystal coupled to a neighbouring paramagnetic center, detected using microwave fluorescence…
Month-long-lifetime microwave spectral holes in an erbium-doped scheelite crystal at millikelvin temperature
Zhiren Wang, Sen Lin, Marianne Le Dantec +9
Rare-earth-ion (REI) ensembles in crystals have remarkable optical and spin properties characterized by narrow homogeneous linewidths relative to the inhomogeneous ensemble broaden…
Quantum-enhanced sensing of axion dark matter with a transmon-based single microwave photon counter
C. Braggio, L. Balembois, R. Di Vora +10
We report an axion dark matter search with a haloscope equipped with a microwave photon counter. The haloscope is a tunable high quality factor 3-dimensional microwave cavity place…
Analytical solutions for optimal photon absorption into inhomogeneous spin memories
József Zsolt Bernád, Michael Schilling, Yutian Wen +4
We investigate for optimal photon absorption a quantum electrodynamical model of an inhomogeneously-broadened spin ensemble coupled to a single-mode cavity. Solutions to this probl…
