Hybrid superconductor-semiconductor quantum devices

International Workshop

Hybrid superconductor-semiconductor quantum devices


The Department of Physics is hosting an international workshop at NTNU Gløshaugen about Hybrid superconductor-semiconductor quantum devices .

Solid-state systems that contain both superconducting and semiconducting elements have become a popular platform for quantum-technological devices in recent years. The rich physics that emerges when superconducting correlations mix with the strongly spin-dependent dynamics in a semiconductor can allow the engineering of quantum states that have a built-in protection against noise and decoherence and can thus yield more accurate sensors or more robust qubits. This workshop will include contributions from the leading theoretical and experimental groups working on super-semi devices, and it thus presents an excellent opportunity to learn about the state of the art in this field.

Time: 15–16 October 2026

Location: D3-114, meetingroom Onsager, Realfagbygget (map)

Registration: Registration for the workshop is free. Please contact Jeroen Danon if you want to participate
