Gabriel Matos

Hi! My name is Gabriel, and I am currently a Research Scientist at Quantinuum working on quantum algorithms and applications of artificial intelligence in quantum computing.

Before joining Quantinuum, I completed a PhD in Theoretical Physics at the University of Leeds supervised by Zlatko Papić and Jiannis Pachos. My research during that time was focused on quantum many-body physics and variational quantum algorithms. You can find my PhD thesis here.

Before that, I completed a BSc and an MSc in Mathematics at the Instituto Superior Técnico, University of Lisbon. You can find my master's thesis here.

You can find a full list of my publications below.
