My research interests lie in quantum information science and quantum gravity, and I generally work on problems in which these fields intersect. I'm particularly interested in cosmology, and a good part of my current research explores what lessons information science can bring to cosmology, and vice versa.

私の研究テーマは量子情報科学と量子重力であり、これらの分野が交差する問題に取り組んでいます。特に宇宙論に興味があり、情報科学が宇宙論にどのような教訓をもたらすか(またその逆も)を主に探求しています。

While classical physics has a distinctively geometric character, and geometry even becomes dynamical in general relativity, quantum theory is by and large an algebraic formalism. The difficulty in formulating a theory of quantum gravity may thus be seen as rooted in the fact that quantum theory is irrevocably non-classical, in the sense that it escapes a geometric description.

My work aims at better demarcating classical and quantum theory. In particular, I am interested in two aspects of this divide. On the one hand, a quantitative characterisation of non-classicality understood as a resource is necessary in order to design algorithms for future quantum computers and to achieve provable quantum advantage. On the other hand, non-classicality understood as a geometric obstruction might prove crucial in departing from classical concepts inherent to general relativity and differential geometry.

I completed my Masters in Mathematics and Physics by the University of Manchester in 2022, where I specialized in Differential Geometry, Gauge Theories and General Relativity. From last October to March, I was working in Prof David Elkouss’s unit – studying several optimizations of Shor’s Quantum Factoring Algorithm applied to RSA integers. In doing so, I had the chance to explore different areas of Quantum Information Theory, like Error Correction and Quantum Networks. During this rotation, I would like to explore the connection between Information Theory and the emergence of Quantum Mechanics, Spacetime and Gravity.
