From Opportunity to Identity: A Journey Across Quantum and Wireless Electronics

This presentation reflects on my ten-year journey at TU Delft, beginning with how I obtained my position and how a series of unexpected events shaped my research identity. I first describe how circumstance and opportunity guided me toward cryogenic electronics for quantum computing, where the central challenge is the precise control and readout of qubits. I then introduce the essential functionalities required for qubit control and measurement, and examine how circuit nonidealities—such as noise and distortion—directly impact gate and readout fidelity. Building on these insights, I review representative controller and readout circuit designs, highlighting both challenges that have been addressed and those that remain open. In the final part of the talk, I reflect on why, despite extensive involvement in quantum computing, ELCA remains my academic home, and on the intellectual satisfaction that wireless communication research continues to offer. The presentation concludes with selected examples from my work on frequency synthesizers, receivers, and phase-locked loops, chosen to be accessible to anyone with a background in linear circuits.
