Simone Severini is an Italian-born British computer scientist. He is currently Professor of Physics of Information at University College London, and Director of Quantum Computing at Amazon Web Services in Seattle.

Work

[edit]

Severini worked in quantum information science and complex systems. Together with Adan Cabello and Andreas Winter, he defined a graph-theoretic framework for studying quantum contextuality, and together with Tomasz Konopka, Fotini Markopoulou, and Lee Smolin, he introduced a random graph model of spacetime called quantum graphity.[2][3] In network theory, he co-introduced the Braunstein–Ghosh–Severini entropy,[4] with applications to quantum gravity.

He served as an editor of Philosophical Transactions of the Royal Society A. In 2015 he was the technical co-founder and one of the first scientific advisors of Cambridge Quantum Computing, with Béla Bollobás, Imre Leader, and Fernando Brandão. He co-founded Phasecraft[5] in 2018 with Toby Cubitt, Ashley Montanaro, and John Morton.
