Superconducting edge contact to a buried Ge quantum well
Dina Sokolova, Davide Costa, Davide Degli Esposti +4
Semiconductor-superconductor hybrid systems form the basis for a broad range of quantum phenomena, such as Andreev bound states, topological superconductivity, and hybrid quantum H…
Light-Hole Spin Qubits in Strained SiGe Lattice-Matched to Ge
Edmondo Valvo, Davide Costa, Patrick Del Vecchio +3
Strained germanium (-Ge) quantum wells on metamorphic SiGe buffers have enabled advanced hole-based spin qubit devices. Alternatively, unstrained Ge with lattice-match…
Buried germanium quantum well proximitised by magnetic field-resilient superconducting platinum iridium germanosilicide
Praveen Viswanathan, Erik Lemmens Sjöstrand, Davide Costa +8
Hybrid superconductor-semiconductor systems provide a versatile platform for quantum technologies, ranging from superconducting-spin interfaces to topological quantum devices. Prog…
Confinement drives valley splitting above 4K in buried silicon quantum wells
Davide Degli Esposti, Emma Catherine Brann, Asser Elsayed +3
Controlling the energy scales of a quantum system is essential for defining robust qubits. In silicon spin qubits, the nearly degenerate conduction-band valleys create a leakage ch…
