Post-doc positions

Germanium-based qubits


A 3-year post-doctoral research position (f/m/d) is available at the LaTEQS laboratory of CEA in Grenoble.The experimental researcher will join an existing team (3PhDs,3staff, 3 staff researchers,2engineers) focusing on the development of novel quantumq electronics based on Ge/Si heterostructures.This emerging material,which embeds high-mobility mobilitymobility two-dimensionalhole gas,has been identified as a promising candidate for spin qubits and hybrid superconductor-semiconductor qubits [1]. Along this line, we have already obtained some first encouraging results, such as the demonstration of ballistic hole transport over long distances[2] and the realization of Josephson field-effect transistors and gate tunable SQUIDs[3].
