Security of Binary Modulated Continuous Variable Quantum Key Distribution under Collective Attacks
Yi-Bo Zhao, Matthias Heid, Johannes Rigas +1
We give an achievable secret key rate of a binary modulated continuous variable quantum key distribution schemes in the collective attack scenario considering quantum channels that…
Security of coherent state quantum cryptography in the presence of Gaussian noise
Matthias Heid, Norbert Lütkenhaus
We investigate the security against collective attacks of a continuous variable quantum key distribution scheme in the asymptotic key limit for a realistic setting. The quantum cha…
Witnessing effective entanglement in a continuous variable prepare&measure setup and application to a QKD scheme using postselection
S. Lorenz, J. Rigas, M. Heid +3
We report an experimental demonstration of effective entanglement in a prepare&measure type of quantum key distribution protocol. Coherent polarization states and heterodyne measur…
Efficiency of coherent state quantum cryptography in the presence of loss: Influence of realistic error correction
Matthias Heid, Norbert Lütkenhaus
We investigate the performance of continuous variable quantum key distribution scheme in a practical setting. More specifically, we take non-ideal error reconciliation procedure in…
