Coexistence of continuous variable QKD with intense DWDM classical channels
Rupesh Kumar, Hao Qin, Romain Alléaume
We demonstrate experimentally the feasibility of continuous variable quantum key distribution (CV-QKD) in dense-wavelength-division multiplexing networks (DWDM), where QKD will typ…
Decoy State Quantum Key Distribution Using Homodyne Detection
S. Hamed Shams Mousavi, Philippe Gallion
In this paper, we propose to use the decoy-state technique to improve the security of the quantum key distribution (QKD) systems based on homodyne detection against the photon numb…
Experimental demonstration of graph-state quantum secret sharing
B. A. Bell, D. Markham, D. A. Herrera-Martí +4
Distributed quantum communication and quantum computing offer many new opportunities for quantum information processing. Here networks based on highly nonlocal quantum resources wi…
Decoherence Effects on the Non-locality of Symmetric States
A. Sohbi, I. Zaquine, E. Diamanti +1
The observation of the non-local properties of multipartite entangled states is of great importance for quantum information protocols. Such properties, however, are fragile and may…
Some applications of uncertainty relations in quantum information
Archan S. Majumdar, Tanumoy Pramanik
We discuss some applications of various versions of uncertainty relations for both discrete and continuous variables in the context of quantum information theory. The Heisenberg un…
Nonlocality and conflicting interest games
Anna Pappa, Niraj Kumar, Thomas Lawson +4
Nonlocality enables two parties to win specific games with probabilities strictly higher than allowed by any classical theory. Nevertheless, all known such examples consider games…
