About me
This is a short CV of Koen Groenland.
I am passionate about deeply understanding novel technology - the inner workings, the impact on society, and how we can teach future generations - even if this requires diving into challenging mathematics or complex societal responses.
I work as a quantum innovation officer at QuSoft and the University of Amsterdam, researching quantum networks and optimal ways to guarantee the identity of the person on the other end of the line. My goal is to investigate the commercial potential of quantum secure identification techniques, which can potentially be brought to the market in collaboration with the Quantum Gateway Foundation.
Between 2020 and 2024, I coordinated the daily activities of Quantum.Amsterdam, which has a mission to accelerate the growth of a commercial ecosystem around quantum technologies in Amsterdam. I was responsible for a broad range of activities, such as business development for public-private partnerships, hosting network activities, setting up new research projects, spreading knowledge and awareness, and various teaching activities for students and professionals (see below). I still work closely together with many partners, such as Quantum Delta NL and the European Quantum Flagship.
My background is in theoretical physics, specializing in the theory of quantum computing. Until February 2020, I was a post-doc at the University of Amsterdam, and until September 2019, I was a PhD candidate at Centrum Wiskunde en Informatica. The focus of my research is on applications of near-term quantum computers: What will be the first useful algorithm that actually has an impact on the real world? How many qubits would that require? What is the right (electrical/optical) signal that we should send into the quantum computer so that it performs the assigned task efficiently?
When not working on quantum stuff, I enjoy playing volleyball (outside hitter), beach volleyball, bouldering, skiing, and gadgets.
