The gatemon : a transmon with a voltage-variable superconductor-semiconductor junction
Jeudi 18 mai 2017 09:30
- Duree : 1 heure
Lieu : Salle « Remy Lemaire » (K223) de l’Institut Néel – au n°25 de la rue des martyrs, Grenoble.
Orateur : Lucas CASPARIS (Niels Bohr Institute, University of Copenhagen)
Recent experiments have demonstrated superconducting transmon qubits with semiconductor nanowire Josephson junctions. These hybrid gatemon qubits utilize field effect tunability singular to semiconductors to allow complete qubit control using gate voltages, potentially a technological advantage over conventional flux-controlled tran smons. In this talk, coherent manipulation of gatemon qubits is discussed. Then the talk will focus on fundamental differences between conventional transmons and gatemons. Further, our efforts to build tunable circuit elements such as switchable couplers are presented. The talk will be concluded by discussing alternative material systems to build hybrid semiconductor-superconductor qubits.
