Entanglement and Quantum Key Distribution
Entanglement in quantum mechanics refers to particles whose individual states cannot be written without reference to the state of other particles. Such states are said to be non-separable, and measurements of the state of one entangled particle alter the state of all entangled particles. This unusual phenomena has applications in quantum teleportation, superdense coding, and various other appli...
متن کاملOne Step Quantum Key Distribution Based on EPR Entanglement
A novel quantum key distribution protocol is presented, based on entanglement and dense coding and allowing asymptotically secure key distribution. Considering the storage time limit of quantum bits, a grouping quantum key distribution protocol is proposed, which overcomes the vulnerability of first protocol and improves the maneuverability. Moreover, a security analysis is given and a simple t...
متن کاملPhoton-Pair States and Violation of CHSH Inequality
Entangled states are important for quantum cryptography, being used in several protocols of quantum key distribution. These provide an alternative to single-photon-based protocols. Entangled states are also important in fundamental terms, in the way that the behavior of these states is contradictory with the predicted by local theories. This contradiction is shown by the violation of Bell’s ine...
متن کاملCoherent state quantum key distribution based on entanglement sudden death
A method for quantum key distribution (QKD) using entangled coherent states is discussed which is designed to provide key distribution rates and transmission distances surpassing those of traditional entangled photon pair QKD by exploiting entanglement sudden death. The method uses entangled electromagnetic signal states of ‘macroscopic’ average photon numbers rather than single photon or entan...
متن کاملCorrigendum: One Step Quantum Key Distribution Based on EPR Entanglement
In the Article, we did not take into account the entanglement swapping that can be caused by eavesdropping efforts. Due to entanglement swapping, in Group 2 of Table 3 and Group 3 of Table 4, the initial states will never lead to a measurement outcome by Eve Ψ Ψ + − 13 24 and Ψ Φ − − 13 24 . Similarly, if after Eve’s measurement Bob performs a measurement using an incorrect sequence, this will ...
