Controlling and reading out a quantum computer requires the generation and acquisition of a multitude of microwave signals. The quality of these signals has a direct impact on the performance of the quantum computer in terms of controllability and readout quality. This requires a signal source with low noise and phase noise, a large bandwidth and low runtime as well as excellent long-term stability. A typical solution uses carefully calibrated IQ mixers but has the disadvantage of a relatively low bandwidth and poor long-term stability. In addition, continuous recalibration is required to function optimally.<\/p>\r\n

Andrea Corna<\/a> will be present at the RF Technology event on behalf of Rohde & Schwarz<\/a> elaborate on a double-superheterodyne concept and how it is used to meet the above requirements without continuous recalibration, but with high bandwidth and a clean spectrum. The speaker will focus on the connection between these features and their impact on real-life quantum computing experiments.<\/p>\r\n

Andrea is an Application Scientist for Quantum Technologies at Zurich Instruments<\/a>He received his PhD in physics from the Universit\u00e9 Grenoble Alpes in France, where he researched silicon quantum dots. At TU Delft he worked on coupling cryogenic control electronics with spin qubits.<\/p>\r\n
