Neither of you are (quantum) physicists, how did you get involved in this project?
Thome — Quantum computing has long since ceased to be an exclusive research field for quantum physicists and has become an interdisciplinary one. Ultimately, the current goal of scaling quantum computers (QCs), which have been proven to work today, relies heavily on electrotechnical components—and this is where we, as high-frequency engineers, come into play.
Heinz — We both have our scientific background in the research of cryogenic and ultra-low-noise amplifiers. Until a few years ago, this was truly a niche topic, typically applied in radio astronomy. However, since the first functional QCs emerged, there has been a whole new interest in this research area. Cryogenic and low-noise electronics are needed for reading out and controlling qubits.
