Security Analysis of Unidimensional Continuous-Variable Quantum Key Distribution Using Uncertainty Relations
We study the equivalence between the entanglement-based scheme and prepare-and-measure scheme of unidimensional (UD) continuous-variable quantum key distribution protocol. Based on this equivalence, the physicality and security of the UD coherent-state protocols in the ideal detection and realistic detection conditions are investigated using the Heisenberg uncertainty relation, respectively. We...
متن کاملSecurity Thresholds of Multicarrier Continuous-Variable Quantum Key Distribution
We prove the secret key rate formulas and derive security threshold parameters of multi-carrier continuous-variable quantum key distribution (CVQKD). In a multicarrierCVQKD scenario, the Gaussian input quantum states of the legal parties are granulatedinto Gaussian subcarrier CVs (continuous-variables). The multicarrier communicationformulates Gaussian sub-channels from the ...
متن کاملSecurity 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 کاملImplementation of continuous-variable quantum key distribution with composable and one-sided-device-independent security against coherent attacks
Secret communication over public channels is one of the central pillars of a modern information society. Using quantum key distribution this is achieved without relying on the hardness of mathematical problems, which might be compromised by improved algorithms or by future quantum computers. State-of-the-art quantum key distribution requires composable security against coherent attacks for a fi...
