Pauli Encodings & Unclonable Encryption
Pierre Botteron, Sébastien Designolle, Omar Fawzi
The unclonable bit question asks whether quantum encryption can prevent an adversary from producing two systems that both reveal the plaintext once the key is disclosed. We introdu…
Nonlocal Games Through Communication Complexity and Quantum Cryptography
Pierre Botteron
This thesis explores foundational aspects of quantum information theory and quantum cryptography. First, we investigate quantum correlations in interactive settings, including the…
Towards Unconditional Uncloneable Encryption
Pierre Botteron, Anne Broadbent, Eric Culf +3
Uncloneable encryption is a cryptographic primitive which encrypts a classical message into a quantum ciphertext, such that two quantum adversaries are limited in their capacity of…
Communication Complexity of Graph Isomorphism, Coloring, and Distance Games
Pierre Botteron, Moritz Weber
In quantum information, nonlocal games are particularly useful for differentiating classical, quantum, and non-signalling correlations. An example of differentiation is given by th…
