Quantum Authentication Using Double Teleportation

A process involving quantum teleportation to teleport a state to two parties in superposition is presented. Then, the process is applied to cryptography. Concretely in this work, we present the process of cryptography authentication using an undefined qubit state and the double quantum teleportation...

Description
Summary:A process involving quantum teleportation to teleport a state to two parties in superposition is presented. Then, the process is applied to cryptography. Concretely in this work, we present the process of cryptography authentication using an undefined qubit state and the double quantum teleportation presented previously. Since quantum cryptography protocols are susceptible of eavesdropping, then such a process is considered through an eavesdropper trying to steal the information to supplant the user of authentication in order to quantify certain limits of applicability.
