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…
