Security of continuous-variable quantum key distribution against general attacks.
We prove the security of Gaussian continuous-variable quantum key distribution with coherent states against arbitrary attacks in the finite-size regime. In contrast to previously known proofs of principle (based on the de Finetti theorem), our result is applicable in the practically relevant finite-size regime. This is achieved using a novel proof approach, which exploits phase-space symmetries...
متن کاملSingle-quadrature continuous-variable quantum key distribution
Most continuous-variable quantum key distribution schemes are based on the Gaussian modulation of coherent states followed by continuous quadrature detection using homodyne detectors. In all previous schemes, the Gaussian modulation has been carried out in conjugate quadratures thus requiring two independent modulators for their implementations. Here, we propose and experimentally test a largel...
متن کاملSecurity against individual attacks for realistic quantum key distribution
The first complete protocol for quantum key distribution (qkd) has been introduced by Bennett and Brassard in 1984 [1] following earlier ideas by Wiesner [2]. Since then, this protocol (BB84 for short) has been implemented by several groups [3–13]. For an overview containing more details about the background, the experimental implementation and the classical evaluation procedure see for example...
متن کاملTrusted noise in continuous-variable quantum key distribution
We address the role of the phase-insensitive trusted preparation and detection noise in the security of a continuous-variable quantum key distribution, considering the Gaussian protocols on the basis of coherent and squeezed states and studying them in the conditions of Gaussian lossy and noisy channels. The influence of such a noise on the security of Gaussian quantum cryptography can be cruci...
