Today the use of lock-in amplifiers is scattered over a very wide field of applications. After a quick introduction to lock-in techniques, this seminar will discuss the specific advantages of digital lock-in technology in terms of speed, multiple parallel signal analysis, and software toolset. We will illustrate these aspects with the practical example of superconducting qubit control and measurement. The seminar will also contain a live demonstration of the Zurich Instruments UHFLI.

Dr. Bruno Küng obtained his PhD in Physics on single-electron counting in semiconductor quantum dots in the group of Klaus Ensslin at ETH Zurich. He continued on the subject of superconducting qubits in the group of Olivier Buisson at CNRS Grenoble. His research work gave him a thorough understanding of the needs of researchers in quantum computing and quantum transport. He joined Zurich Instruments in 2015 as an expert on quantum applications.
