Teleportation based non-degenerate discordant remote state preparation

摘要

Remotely preparing quantum states, which possess some desired features, is an important task for future quantum network host providers. On the other hand, the non-degenerate discordant two-qubit states, the states with different left and right quantum discords, is necessary for the implementation of some quantum information and quantum computation processes. This paper presents a new preparation scheme of such states realized by the asymmetric quantum correlation teleportation (AQCT) protocol i.e. quantum correlation teleportation via two different quantum channels. In this way, some properties of AQCT protocol are studied to achieve the most appropriate and least expensive procedure of preparing the asymmetric discordant two-qubit quantum states.
