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…
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…
Entanglement verification for quantum key distribution systems with an underlying bipartite qubit-mode structure
Johannes Rigas, Otfried Gühne, Norbert Lütkenhaus
We consider entanglement detection for quantum key distribution systems that use two signal states and continuous variable measurements. This problem can be formulated as a separab…
