Maximally nonlocal theories cannot be maximally random
Gonzalo de la Torre, Matty J. Hoban, Chirag Dhara +2
Correlations that violate a Bell Inequality are said to be nonlocal, i.e. they do not admit a local and deterministic explanation. Great effort has been devoted to study how the am…
Maximal quantum randomness in Bell tests
Chirag Dhara, Giuseppe Prettico, Antonio Acin
The non-local correlations exhibited when measuring entangled particles can be used to certify the presence of genuine randomness in Bell experiments. While non-locality is necessa…
Can bipartite classical information resources be activated?
Giuseppe Prettico, Antonio Acin
Non-additivity is one of the distinctive traits of Quantum Information Theory: the combined use of quantum objects may be more advantageous than the sum of their individual uses. N…
Superactivation, unlockability, and secrecy distribution of bound information
Giuseppe Prettico, Joonwoo Bae
Bound information, a cryptographic classical analogue of bound entanglement, is defined as classical secret correlations from which no secret key can be extracted. Its existence wa…
Perfect Quantum Privacy Implies Nonlocality
Remigiusz Augusiak, Daniel Cavalcanti, Giuseppe Prettico +1
Private states are those quantum states from which a perfectly secure cryptographic key can be extracted. They represent the basic unit of quantum privacy. In this work we show tha…
