Erratum: Continuous Variable Quantum Key Distribution: Finite-Key Analysis of Composable Security Against Coherent Attacks [Phys. Rev. Lett. 109, 100502 (2012)]

TL;DR: Quantum cryptography is arguably the fastest growing area in quantum information science as mentioned in this paper, and many quantum key distribution protocols have been proposed, both theoretically and experimentally, over the last few decades.

TL;DR: A control scheme for two-mode squeezed vacuum states at the telecommunication wavelength of 1550 nm is experimentally demonstrated and it is shown that stable phase control mechanisms are necessary but difficult to achieve.

TL;DR: It is concluded that for a wide range of pragmatic system models, CS-QKD with information-theoretic security in the satellite-to-Earth channel is feasible.

TL;DR: In this paper, the authors proposed a long-distance continuous-variable quantum key distribution (CVQKD) with four-state protocol using non-Gaussian state-discrimination detection.

TL;DR: This work proposes several methods for quantum key distribution (QKD) based on the generation and transmission of random distributions of coherent or squeezed states, and shows that they are secure against individual eavesdropping attacks.

TL;DR: A new coherent state quantum key distribution protocol that eliminates the need to randomly switch between measurement bases and offers the further advantage of simplicity compared to all previous protocols which, to date, have relied on switching.

TL;DR: It is proved that the Gaussian unitary attack is optimal for all the considered bounds on the key rate when the first and second momenta of the canonical variables involved are known by the honest parties.

TL;DR: A general method for studying properties of quantum channels acting on an n-partite system, whose action is invariant under permutations of the subsystems, and a simple proof for the fact that security of a discrete-variable quantum key distribution protocol against collective attacks implies security of the protocol against the most general attacks.
