Teleportation of an N-photon Greenberger-Horne-Zeilinger (GHZ) polarization-entangled state using linear optical elements

Yan Xia, Jie Song, Pei-Min Lu +1 more

With one pair of photons' polarization-entangled state as the quantum channel, we present an explicit generalized linear optical protocol for perfectly teleporting an N-photon Greenberger-Horne-Zeilinger (GHZ) polarization-entangled state from a sender to a receiver using only one two-photon polarization-entangled state as the quantum channel. This protocol has the advantage of transmitting much fewer photons and classical information for teleporting the N-photon GHZ polarization-entangled state than others, and the proposed setup involves simple linear optical elements, photon polarization-entangled states, and conventional photon detectors. These make the present protocol more realizable in experiments.

Secure and Efficient n-Qubit Entangled State Teleportation Using Partially Entangled GHZ Channels and Optimal POVM

Animesh Banik, Md. Shihab Khan, Rafid Masrur Khan +2 more

We introduce an efficient and versatile quantum teleportation protocol for specific types of n-qubit entangled states. By employing a partially entangled Greenberger-Horne-Zeilinger (GHZ) state as the quantum channel and an optimal Positive Operator-Valued Measure (POVM) based on an improved reciprocal state formulation, we achieve unambiguous state discrimination. The scheme has been generalized to support various entangled state configurations and demonstrates a notable reduction in classical communication costs for these states compared to standard Bell-basis teleportation. Its capacity for integration with conventional protocols is pivotal, enhancing quantum hop-by-hop communication security by allowing strategic choices in quantum channel and teleportation strategy

Quantum teleportation

Sergey N. Andrianov, А. С. Алимбекова

In 1993, C.H. Bennet et. al. had proposed the protocol for quantum teleportation of unknown quantum state. Now, this phenomenon was observed experimentally and numerous applications in quantum telecommunications and informatics are proposed. This method of communication is not direct because it uses classical besides quantum channel. We propose here another scheme where protocol can be established before information transmission and then information is transmitted through quantum electro-dynamic channel of interaction between particles with entangled states. With that, parametric interaction between photons is implemented for coupling of information to this interaction channel and subsequent read out of information. In this scheme, the pair of photons with entangled polarization states is used and parametric interaction trough the field of virtual photons serves as interaction channel.
