Keywords: qubits, mesoscopic physics, superconductivity, low noisel, ow temperature and high frequency measurements

The position aims to investigate the dynamical properties of helical Andreev qubits, i.e. qubits based on two level systems made from the ground and excited Andreev levels of a Josephson junction built with 1D helical states. Helical states are spin-momentum locked, meaning that their spin orientation is given by the propagation direction. They are found at the edges of 2D topological insulators or at the hinges of 3D second-order topological insulators.

The candidate must have a PhD in Physics, and preferably experience with mesoscopic physics, superconductivity, low noise, low temperature and high frequency measurements.
