Profile

Biography

I did my MSc in physics at the Budapest University of Technology and Economics, under the supervision of Péter Vrana (Institute of Mathematics). After that, in 2015 I moved to Gdansk, where I did my PhD in physics at the University of Gdansk/National Quantum Information Centre (KCIK), supervised by Marcin Pawłowski. I then joined the Quantum Information Theory group led by Antonio Acín at ICFO, Barcelona in 2020 as a postdoctoral researcher, where I later held a Marie Skłodowska-Curie COFUND PROBIST Postdoctoral Fellowship for two years.

I joined the Department of Mathematics at the University of York in 2023 as a Lecturer in Mathematics and Quantum Technologies.

Research

Overview

Quantum theory predicts phenomena that do not have a classical physical counterpart. Quantum measurements are intrinsically random and quantum systems can be correlated to one another more strongly than can be explained by classical physics. In my research, I am working on the mathematical characterisation of these purely quantum phenomena, such as Bell non-locality, contextuality or incompatibility.

Such quantum phenomena also allow us to design quantum information processing protocols that outperform any protocol based on a classical physical description. Even further, quantum theory makes it possible to design devices such as random number generators and cryptographic devices whose security is based solely on the laws of nature. My research also tackles the problem of identifying quantum properties and phenomena that are relevant to quantum advantage in information processing, and I am working on the certification of quantum devices in a black-box scenario, based only on observable data such as measurement outcome statistics.
