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…
Conductance Plateaus at Quantum Hall Integer Filling Factors in Germanium Quantum Point Contacts
Karina Hudson, Davide Costa, Davide Degli Esposti +2
Constricting transport through a one-dimensional quantum point contact in the quantum Hall regime enables gate-tunable selection of the edge modes propagating between voltage probe…
Buried unstrained germanium channels: a lattice-matched platform for quantum technology
Davide Costa, Patrick Del Vecchio, Karina Hudson +8
Strained Ge (-Ge) and strained Si (-Si) buried quantum wells have enabled advanced spin-qubit quantum processors. However, in the absence of suitable lattice-matched substrat…
QARPET: A Crossbar Chip for Benchmarking Semiconductor Spin Qubits
Alberto Tosato, Asser Elsayed, Federico Poggiali +5
Large-scale integration of semiconductor spin qubits into quantum processors hinges on the ability to characterize quantum components at scale, a task challenged by their operation…
