Security of two quantum cryptography protocols using the same four qubit states
Cyril Branciard, Nicolas Gisin, Barbara Kraus +1
The first quantum cryptography protocol, proposed by Bennett and Brassard in 1984 (BB84), has been widely studied in the last years. This protocol uses four states (more precisely,…

Quantum memory for non-stationary light fields based on controlled reversible inhomogeneous broadening
B. Kraus, W. Tittel, N. Gisin +3
We propose a new method for efficient storage and recall of non-stationary light fields, e.g. single photon time-bin qubits, in optically dense atomic ensembles. Our approach to qu…

An information-theoretic security proof for QKD protocols
R. Renner, N. Gisin, B. Kraus
We present a new technique for proving the security of quantum key distribution (QKD) protocols. It is based on direct information-theoretic arguments and thus also applies if no e…
