Quantum key distribution system using dual-threshold homodyne detection
In this work we present the principles of a flexible quantum key distribution (QKD) system using quadraturephase-shift-keying (QPSK) base and symbol encoding and dualthreshold bala...

The Universal Composable Security of Quantum Key Distribution
The existing unconditional security definitions of quantum key distribution (QKD) do not apply to joint attacks over QKD and the subsequent use of the resulting key. In this paper...

Security Aspects of Practical Quantum Cryptography
The use of quantum bits (qubits) in cryptography holds the promise of secure cryptographic quantum key distribution schemes. Unfortunately, the implemented schemes are often operat...
