A Quantum Superposition of Black Hole Evaporation Histories: Recovering Unitarity
Ali Akil, Lorenzo Giannelli, Leonardo Modesto +3
Black hole evaporation is one of the most striking phenomena at the interface between gravity and quantum physics. In Hawking's semi-classical treatment, where matter is quantum me…

Information-theoretic derivation of energy, speed bounds, and quantum theory
Lorenzo Giannelli, Giulio Chiribella
We provide a derivation of quantum theory in which the existence of an energy observable that generates the reversible dynamics follows directly from information-theoretic principl…

Bit Commitment in Operational Probabilistic Theories
Lorenzo Giannelli
The aim of this thesis project is to investigate the bit commitment protocol in the framework of operational probabilistic theories. In particular a careful study is carried on the…
