Quentin E.J. Schmidt, post-doctoral researcher in the QuTech institute of Delft University of Technology, Netherlands will present “Cryogenic CMOS Electronics for Silicon Spin Qubit–Based Quantum Computers”.

Abstract:

Quantum computers offer the potential to further enhance computing capability. Nonetheless, millions of qubits, usually operating at cryogenic temperatures, will be required. Controlling, manipulating, reading out, and correcting these millions of qubits represents a major challenge, for which cryogenic CMOS electronics (Cryo-CMOS) has been demonstrated to be essential. This presentation will address the challenges faced in developing Cryo-CMOS and provide an overview of current circuit developments for the control, manipulation, and correction of silicon spin qubits. Finally, it will detail the development of readout circuits to extract the sensitive quantum information from the cryostat. 

 

Biography:

Quentin E.J. Schmidt received B.Sc. and M.Sc. degrees in electrical engineering from the University of Strasbourg, Strasbourg, France, in 2019 and 2021, respectively. He pursued his Ph.D. at CEA-Leti in Grenoble, France, focusing on analog integrated circuits design and test for cryogenic applications, targeting qubit readout with low-power transimpedance amplification. He is currently a post-doctoral researcher at TU Delft, working on analog cryogenic IC design for spin qubits applications.
