Freek Witteveen selected for QDNL’s Top Talent Initiative
QDNL is pleased to announce Freek Witteveen, a senior researcher at QuSoft and CWI, as a recipient of funding and mentorship through our Top Talent Initiative (TTI).
Freek’s work sits at the intersection of physics, mathematics, and computer science – and he effectively aims to move ideas from one domain to another. Through the study of quantum tensor network states, he explores which quantum systems can be examined using a classical computer and which require quantum computation. This research is relevant for both quantum algorithm design and the development of classical algorithms for quantum systems.
We spoke further with Freek about his interdisciplinary research into quantum computing algorithms and the importance of pairing the theoretical with the practical.
Designing the conditions to simulate complex quantum systems
From Freek’s perspective, one of the most important applications of quantum computers is the simulation of complex quantum systems, such as molecules and materials, where quantum effects are significant. A key aspect of his research is developing algorithms that make these simulations more effective.
“Current quantum computers are not yet outperforming classical computers, except in very exceptional cases,” says Freek, “But quantum computers are already influencing the current understanding of quantum physics by offering us an alternative computational perspective on quantum states.”
Freek goes on to explain that it’s important to understand the difference between states that can be efficiently described on a classical computer and states that require a quantum computer. His work on tensor network states helps build that understanding.
Pairing the theoretical, philosophical and the practical
Quantum computing originated from very theoretical, almost philosophical, ideas. Modern practices are focusing more heavily on quantum applications in real-world scenarios. Freek plans to continue to bridge these two sides.
“We are now living in an exciting time where the field is transitioning to large-scale engineering and is trying to realise useful applications. One of the aspects of quantum computing that I find very attractive is the combination of fundamental physics and deep theoretical ideas with very concrete challenges and applications.”
Freek also firmly believed that both theoretical concepts and the rigorous analysis of algorithms will be equally essential in guiding the future development of quantum computing and quantum algorithms.
Looking ahead
In addition to his research, Freek will begin teaching in the Master’s programme in Quantum Computer Science at the University of Amsterdam.
“I really enjoy teaching, and I look forward to educating the future generation of quantum scientists and software engineers.”
