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…
Quantum Secret Sharing with error correction
Aziz Mouzali, Fatiha Merazka, Damian Markham
We investigate in this work a quantum error correction on a five-qubits graph state used for secret sharing through five noisy channels. We describe the procedure for the five, sev…
