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…

We demonstrate a transmon qubit readout based on the nonlinear response to a drive of polaritonic meters in-situ coupled to the qubit. Inside a 3D readout cavity, we place a transm…
Propagating Quantum Microwaves: Towards Applications in Communication and Sensing
Mateo Casariego, Emmanuel Zambrini Cruzeiro, Stefano Gherardini +22
The field of propagating quantum microwaves has started to receive considerable attention in the past few years. Motivated at first by the lack of an efficient microwave-to-optical…
Energetics of a Single Qubit Gate
Jeremy Stevens, Daniel Szombati, Maria Maffei +10
Qubits are physical, a quantum gate thus not only acts on the information carried by the qubit but also on its energy. What is then the corresponding flow of energy between the qub…
Dissipative stabilization of squeezing beyond 3 dB in a microwave mode
