An ultracompact dilution refrigerator for fast quantum device characterization
Clment Geffroy, Dorian Nicolas, Eric Eyraud +10
Rapid thermal cycling is a central bottleneck in the development of superconducting quantum devices: conventional dilution refrigerators require cooldowns of a day or more and subs…

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…
