Quantum correlations in and beyond quantum entanglement in bipartite continuous variable systems [PDF]
, 2012 This thesis explores the role of non-classical correlations in bipartite continuous variable quantum systems, and the approach taken is three-fold. We show that given two initially entangled atomic ensembles, it is possible to probabilistically increase ...

Experimental study of continuous variable quantum key distribution [PDF]
2015 11th International Conference on Information Assurance and Security (IAS), 2015 It has been proven in the literature that the main technological factors limiting the communication rates of quantum cryptography systems by single photon are mainly related to the choice of the encoding method. In fact, the efficiency of the used sources is very limited, at best of the order of a few percent for the single photon sources and the ...

Frequency-multiplexed entanglement for continuous-variable quantum key distribution [PDF]
Photonics Research, 2021 Quantum key distribution with continuous variables already uses advantageous high-speed single-mode homodyne detection with low electronic noise at room temperature. Together with continuous-variable information encoding to nonclassical states, the distance for secure key transmission through lossy channels can approach 300 km in current optical fibers.

Low-Dimensional Reconciliation for Continuous-Variable Quantum Key Distribution
Applied Sciences, 2018 We propose an efficient logical layer-based reconciliation method for continuous-variable quantum key distribution (CVQKD) to extract binary information from correlated Gaussian variables. We demonstrate that by operating on the raw-data level, the noise
