Post-selection technique for quantum channels with applications to quantum cryptography
Matthias Christandl, Robert Koenig, Renato Renner
We propose a general method for studying properties of quantum channels acting on an n-partite system, whose action is invariant under permutations of the subsystems. Our main resu…
A de Finetti representation theorem for infinite dimensional quantum systems and applications to quantum cryptography
Renato Renner, J. Ignacio Cirac
According to the quantum de Finetti theorem, if the state of an N-partite system is invariant under permutations of the subsystems then it can be approximated by a state where almo…
Security Bounds for Quantum Cryptography with Finite Resources
Valerio Scarani, Renato Renner
A practical quantum key distribution (QKD) protocol necessarily runs in finite time and, hence, only a finite amount of communication is exchanged. This is in contrast to most of t…
Hidden variable models for quantum theory cannot have any local part
Roger Colbeck, Renato Renner
It was shown by Bell that no local hidden variable model is compatible with quantum mechanics. If, instead, one permits the hidden variables to be entirely non-local, then any quan…
Smooth Renyi Entropies and the Quantum Information Spectrum
Nilanjana Datta, Renato Renner
Many of the traditional results in information theory, such as the channel coding theorem or the source coding theorem, are restricted to scenarios where the underlying resources a…
