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…
Implementing Non-Projective Measurements via Linear Optics: an Approach Based on Optimal Quantum State Discrimination
Peter van Loock, Kae Nemoto, William J. Munro +2
We discuss the problem of implementing generalized measurements (POVMs) with linear optics, either based upon a static linear array or including conditional dynamics. In our approa…
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…
Upper bound on the secret key rate distillable from effective quantum correlations with imperfect detectors
Tobias Moroder, Marcos Curty, Norbert Lütkenhaus
We provide a simple method to obtain an upper bound on the secret key rate that is particularly suited to analyze practical realizations of quantum key distribution protocols with…
Optimal Unambiguous State Discrimination of two density matrices and its link with the Fidelity
Philippe Raynal, Norbert Lütkenhaus
Recently the problem of Unambiguous State Discrimination (USD) of mixed quantum states has attracted much attention. So far, bounds on the optimum success probability have been der…
