Journal ArticleDOI
The security of practical quantum key distribution
Valerio Scarani,Helle Bechmann-Pasquinucci,Nicolas J. Cerf,Miloslav Dušek,Norbert Lütkenhaus,Momtchil Peev +5 more
TL;DR: Essential theoretical tools that have been developed to assess the security of the main experimental platforms are presented (discrete- variable, continuous-variable, and distributed-phase-reference protocols).
Journal ArticleDOI
Gaussian quantum information
Christian Weedbrook,Stefano Pirandola,Raúl García-Patrón,Nicolas J. Cerf,Timothy C. Ralph,Jeffrey H. Shapiro,Seth Lloyd +6 more
TL;DR: This review focuses on continuous-variable quantum information processes that rely on any combination of Gaussian states, Gaussian operations, and Gaussian measurements, including quantum communication, quantum cryptography, quantum computation, quantum teleportation, and quantum state and channel discrimination.
Gaussian quantum information
Christian Weedbrook,Stefano Pirandola,Raúl García-Patrón,Nicolas J. Cerf,Timothy C. Ralph,Jeffrey H. Shapiro,Seth Lloyd +6 more
TL;DR: In this article, a review of the state of the art in continuous-variable quantum information processing can be found, ranging from the basic theoretical tools and landmark experimental realizations to the most recent successful developments.
Journal ArticleDOI
Quantum key distribution using gaussian-modulated coherent states
Frédéric Grosshans,Gilles Van Assche,Jérôme Wenger,Rosa Brouri,Nicolas J. Cerf,Philippe Grangier +5 more
TL;DR: This work proposes and experimentally demonstrate a quantum key distribution protocol based on the transmission of gaussian-modulated coherent states and shot-noise-limited homodyne detection, which is in principle secure for any value of the line transmission, against gaussian individual attacks based on entanglement and quantum memories.
Journal ArticleDOI
Security of Quantum Key Distribution Using d -Level Systems
TL;DR: The information gained by a potential eavesdropper applying a cloning-based individual attack is derived, along with an upper bound on the error rate that ensures unconditional security against coherent attacks.
