Coherence Limits in Interference-Based cos(2) Qubits
S. Messelot, A. Leblanc, J. -S. Tettekpoe +4
We investigate the coherence properties of parity-protected qubits based on interferences between two Josephson elements in a superconducting loop. We show that qubit i…
Gate-tunable Josephson parametric amplifiers based on semiconductor nanowires
Raphael Rousset-Zenou, Nicolas Aparicio, Simon Messelot +5
Superconductor-semiconductor hybrid materials have been extensively used for experiments on electrically tunable quantum devices. Notably, Josephson junctions utilizing nanowire we…
Gate-tunable spectrum and charge dispersion mitigation in a graphene superconducting qubit
Nicolas Aparicio, Simon Messelot, Edgar Bonet-Orozco +5
Controlling the energy spectrum of quantum-coherent superconducting circuits, i.e. the energies of excited states, the circuit anharmonicity and the states' charge dispersion, is e…
Laser patterning of the room temperature van der Waals ferromagnet 1-CrTe
Tristan Riccardi, Suman Sarkar, Anike Purbawati +19
Lamellar crystalline materials, whose layers are bond by van der Waals forces, can be stacked to form ultrathin artificial heterostructures, and in particular vertical magnetic jun…
