WebMay 30, 2024 · Quantum key distribution (QKD), another name for quantum cryptography, is the most advanced subfield of quantum information and communication technology (QICT). The first QKD protocol was proposed in 1984, and since then, more protocols have been proposed. It uses quantum mechanics to enable secure exchange of cryptographic keys. … WebA theorem by Shannon and the Holevo theorem impose that the efficiency of any protocol for quantum key distribution, E, defined as the number of secret (i.e., allowing …

WebOct 9, 2024 · The security of quantum key distribution has traditionally been analyzed in either the asymptotic or non-asymptotic regimes. In this paper, we provide a bridge between these two regimes, by determining second-order coding rates for key distillation in quantum key distribution under collective attacks. Our main result is a formula that characterizes … WebQuantum key distribution (QKD; see [1,2] for reviews) is the branch of quantum information science, whose goal is to develop methods (protocols) that allow two trusted parties to share a random secret key so that its security is provided by the very laws of quantum physics.The key can be then used in the one-time pad cryptographic system [], which was … supersonic mp3 cd player with usb aux inputs
