2 de mai. de 2024 · This leads us to define and formalize the concept of `short-range' and `long-range' quantum correlations in routed Bell experiments. We show that these correlations can be characterized through standard semidefinite-programming hierarchies for non-commutative polynomial optimization.
Há 5 dias · Quantum computing. Quantum System One, a quantum computer by IBM from 2019 with 20 superconducting qubits [1] A quantum computer is a computer that takes advantage of quantum mechanical phenomena. On small scales, physical matter exhibits properties of both particles and waves, and quantum computing leverages this behavior, specifically quantum ...
14 de mai. de 2024 · Charles Bennett, Gilles Brassard, Claude Crépeau, Richard Jozsa, Asher Peres, and William Wootters. Teleporting an unknown quantum state via dual classical and Einstein-Podolsky-Rosen channels.
Há 3 dias · It led to the 1984 discovery of quantum key distribution protocols, most famously BB84 by Charles H. Bennett and Gilles Brassard and E91 by Artur Ekert. Although BB84 does not use entanglement, Ekert's protocol uses the violation of a Bell's inequality as a proof of security.
Há 2 dias · BB84 Protocol: One of the first and most widely known QKD protocols, developed by Charles Bennett and Gilles Brassard in 1984. It uses polarized photons to transmit the key, with the security guaranteed by the principles of quantum mechanics.
27 de abr. de 2024 · Developed by Charles Bennett and Gilles Brassard in 1984. Uses a single-photon source to transmit quantum states (0s and 1s) over a quantum channel. Basis reconciliation and error correction techniques are employed to ensure secure key distribution.
16 de mai. de 2024 · Bref retour en cour, jeudi matin, à Laval de Gilles Brassard, cet homme accusé du meurtre de sa conjointe atteinte d’Alzheimer, survenu le 30 septembre dans une résidence pour aîné à Terrebonne. L'avocate de la Défense, Me Elfriede Duclervil, a annoncé au juge Simon Brisson-Dolci que son client renonçait à son enquête préliminaire ...
