Electron paramagnetic resonance of Dy-doped CaWO: spin Hamiltonian, crystal-field analysis, and linear electric field effect
Achuthan Manoj Kumar, Larissa Aboudem-Joumessi, Remy Dassonneville +6
We report an electron paramagnetic resonance (EPR) study of Dy in CaWO single crystals spanning dopant concentrations from 80~ppb to 247~ppm. The factors of the grou…
Strongly anisotropic non-Kramers electron spin as a quantum coherence probe of angular fluctuations
Achuthan Manoj Kumar, Remy Dassonneville, Guillaume Gerbaud +5
Strongly anisotropic non-Kramers rare-earth ions combine giant longitudinal g-factors with a vanishing transverse component imposed by time-reversal symmetry, a combination that ma…
Absence of Charge Offset Drift in a Transmon Qubit
Adria Rospars, Hector Hutin, Yannick Seis +8
Superconducting quantum circuits are sensitive to their electrostatic environment: uncontrolled charges accumulating on the electrodes of a Josephson junction shift the energy leve…
Exploring electron spin dynamics in spin chains using defects as a quantum probe
L. Soriano, A. Manoj-Kumar, G. Gerbaud +7
We investigate the quantum dynamics of the electron spin resonance of topological defects (edge state) in dimerized chains. These objects are discontinuities of the spin chain prot…
Observation and mitigation of microwave echoes from dielectric defects in Josephson traveling wave amplifiers
Matteo Boselli, Joel Grebel, Ambroise Peugeot +3
Amplifying microwave signals with a noise close to the minimum imposed by quantum mechanics is now routinely performed with superconducting quantum devices. In particular, Josephso…
Amplifying microwave pulses with a single qubit engine fueled by quantum measurements
Rémy Dassonneville, Cyril Elouard, Romain Cazali +4
Recent progress in manipulating individual quantum systems enables the exploration of engines exploiting non-classical resources. One of the most appealing is the energy provided b…
