Postdoctoral Fellow - Ultrafast Spin Qubit Readout for Quantum Computing

Develop and implement a platform for dynamical optical Q-switching of superconducting resonators to achieve ultrafast and nondestructive readout of gate-defined spin qubits. Conduct high-frequency opto-transport experiments at cryogenic temperatures. Design, build, and optimize experimental setups for optoelectronic measurements. Collaborate closely with consortium partners, particularly the groups of Prof. Richard Warburton and Dr. Andreas Kuhlmann.

The Quantum Opto-Electronics Group (QOEG) , led by Prof. Dr. Tomasz Smoleński at the Department of Physics, University of Basel, invites you to join this groundbreaking project within the NCCR SPIN consortium. This position offers the unique opportunity to make significant contributions to the field. You will work at the forefront of quantum research, contributing to a platform for dynamical Q-switching of superconducting resonators.
