The Quantum Devices Lab primarily focuses on quantum devices built from hybrid superconductor-semiconductor materials (“super-semis"). Super-semis promise new functionalities, combining the simplicity and long-range coherence of microwaves routed around millimetre-scale planar circuits with the rich bandstructure and field-effect tunability of semiconductors.

Our research is currently divided into the two following themes:

Reserach blocks

Quantum Jo-FETs

Josephson Field-Effect Transistors (Jo-FETs) are semiconductor channels sandwiched between superconducting contacts. Jo-FETs introduce voltage-controlled nonlinearities in quantum circuits.

Topological Phases

Topological quantum devices have electronic properties are governed by bandstructure topology. Excitations in these systems are localised along surfaces and edges where they avoid bulk noise and disorder, potentially improving the performance of quantum devices like qubits and metrological standards.
