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…
Direct measurement of a current phase relation in a graphene superconducting quantum interference device
Simon Messelot, Nicolas Aparicio, Elie de Seze +5
In a Josephson junction, the current phase relation relates the phase variation of the superconducting order parameter, , between the two superconducting leads connected through…
Tamm Cavity in the Terahertz Spectral Range
Simon Messelot, Clémentine Symonds, Joël Bellessa +5
Electromagnetic resonators, which are based on optical cavities or electronic circuits, are key elements to enhance and control light-matter interaction. In the THz range, current…
Ultrasensitive Photoresponse of Graphene Quantum Dot in the Coulomb Blockade Regime to THz Radiation
E. Riccardi, S. Massabeau, F. Valmorra +11
Graphene quantum dots (GQDs) have recently attracted considerable attention, with appealing properties for terahertz (THz) technology. This includes the demonstration of large ther…
