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…
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…
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…
Opto-RF transduction in Er:CaWO
Thierry Chanelière, Rémi Dardaillon, Pierre Lemonde +5
We use an erbium doped CaWO crystal as a resonant transducer between the RF and optical domains at 12 GHz and 1532 nm respectively. We employ a RF resonator to enhance the spin…
Electron-spin spectral diffusion in an erbium doped crystal at millikelvin temperatures
Milos Rančić, Marianne Le Dantec, Sen Lin +9
Erbium-doped crystals offer a versatile platform for hybrid quantum devices because they combine magnetically-sensitive electron-spin transitions with telecom-wavelength optical tr…
Radiative cooling of a spin ensemble
Bartolo Albanese, Sebastian Probst, Vishal Ranjan +8
Physical systems reach thermal equilibrium through energy exchange with their environment, and for spins in solids the relevant environment is almost always the host lattice in whi…
Pulsed electron spin resonance spectroscopy in the Purcell regime
Vishal Ranjan, Sebastian Probst, Bartolo Albanese +8
When spin relaxation is governed by spontaneous emission of a photon into the resonator used for signal detection (the Purcell effect), the relaxation time depends on the spi…
Stabilizing entanglement via symmetry-selective bath engineering in superconducting qubits
M. E. Schwartz, L. Martin, E. Flurin +4
Bath engineering, which utilizes coupling to lossy modes in a quantum system to generate non-trivial steady states, is a tantalizing alternative to gate- and measurement-based quan…
