The Role of piracy in quantum proofs
Anne Broadbent, Alex B. Grilo, Supartha Podder +1
A well-known feature of quantum information is that it cannot, in general, be cloned. Recently, a number of quantum-enabled information-processing tasks have demonstrated various f…
High-Dimensional Quantum Certified Deletion
Felix Hufnagel, Anne Broadbent, Ebrahim Karimi
Certified deletion is a protocol which allows two parties to share information, from Alice to Bob, in such a way that if Bob chooses to delete the information, he can prove to Alic…
Quantum delegation with an off-the-shelf device
Anne Broadbent, Arthur Mehta, Yuming Zhao
Given that reliable cloud quantum computers are becoming closer to reality, the concept of delegation of quantum computations and its verifiability is of central interest. Many mod…
Uncloneable Cryptographic Primitives with Interaction
Anne Broadbent, Eric Culf
Much of the strength of quantum cryptography may be attributed to the no-cloning property of quantum information. We construct three new cryptographic primitives whose security is…
Extending the Known Region of Nonlocal Boxes that Collapse Communication Complexity
Pierre Botteron, Anne Broadbent, Marc-Olivier Proulx
Non-signalling boxes (NS) are theoretical resources defined by the principle of no-faster-than-light communication. They generalize quantum correlations, and some of them are known…
Categorical composable cryptography: extended version
Anne Broadbent, Martti Karvonen
We formalize the simulation paradigm of cryptography in terms of category theory and show that protocols secure against abstract attacks form a symmetric monoidal category, thus gi…
