Abstract

A scheme for teleporting two-mode entangled photon states with the successful probability 33.3% is proposed. In the scheme, the teleporte d qubit is two-mode photon entangled states, and two pairs of EPR pair are used as quantum channel between a sender and a receiver. This procedure is achieved by using two 50/50 symmetric beam splitters and four photon number detectors wit h the help of classical information.

A scheme for teleporting two mode entangled photon states with the successful probability 33.3% is proposed. In the scheme, the teleported qubit is two mode photon entangled states, and two pairs of EPR pair are used as quantum channel between a sender and a receiver. This procedure is achieved by using two 50/50 symmetric beam splitters and four photon number detectors with the help of classical information.

Quantum teleportation of entanglement using four-particle entangled states

Sergey A. Podoshvedov

We present a model to realise a probabilistic quantum teleportation of two-particle mode entangled state through the four-photon quantum channel. Four modes of the two-photon mode entangled state are directly transferred to other spatial four modes of the quantum channel with success probability of 50%. The quantum protocol operates in space of photon number states. A Bell state measurement with four beam splitters and four pairs of detectors in the teleportation protocol is accomplished in the fourfold coincidence basis.

Quantum teleportation of entangled coherent states

Xiaoguang Wang

We propose a simple scheme for the quantum teleportation of both bipartite and multipartite entangled coherent states with the success probability 1/2. The scheme is based only on linear optical devices such as beam splitters and phase shifters, and two-mode photon number measurements. The quantum channels described by the multipartite maximally entangled coherent states, are readily made by the beam splitters and phase shifters.

Teleportation of a two-particle four-component squeezed vacuum state by linear optical elements

陈慧娜 Huina Chen, 刘金明 Jinming Liu

We present a linear optical scheme for achieving a unity fidelity teleportation of a two-particle fourcomponent squeezed vacuum state using two entangled squeezed vacuum states as quantum channel.The devices used are beam splitters and ideal photon detectors capable of distinguishing between odd and even photon numbers.Moreover, we also obtain the success probability of the teleportation scheme.

Teleportation of the three-particle entangled state by two EPR pairs

Shou Zhang

A scheme for teleporting a three-particle entangled state is proposed.In the scheme, two EPR pairs are chosen as quantum channels which shared by the sender and the receiver.By introducing an additional qubit and performing CNOT operation as well as appropriate unitary transformation,the three-particle entangled state can be teleported probabilistically.

Scheme for Realizing Probabilistic Teleportation of Bipartite Photonic States via Linear Optical Elements

Dong Ping, Lin Ji-Cheng, Yang Ming +1 more

We propose a probabilistic scheme for realizing teleportation of bipartite photonic states using linear optical elements where only requires a two-photon Bell state used as quantum channel. It reduces the requirement of the entanglement of quantum channel, but requires an additional photon and an auxiliary maximally entangled photon pair locally.
