Abstract

We propose a scheme for creating long-distance quantum entanglement, which can be used to teleport quantum states of an atom unconditionally via measurements of all four Bell states, using a method of sequential elimination.

Long Distance, Unconditional Teleportation of Atomic States via Complete Bell State Measurements

Seth Lloyd, M. S. Shahriar, Jeffrey H. Shapiro +1 more

We propose a scheme for creating and storing quantum entanglement over long distances. Optical cavities that store this long-distance entanglement in atoms could then function as nodes of a quantum network, in which quantum information is teleported from cavity to cavity. The teleportation is conducted unconditionally via measurements of all four Bell states, using a novel method of sequential elimination.

We present a scheme using four two-level atoms and a bimodal cavity to get approximate conditional teleportation of an arbitrary entangled atomic state without using the Bell-state measurement.

Near-complete teleportation of a superposed coherent state

Yong Wook Cheong, Hyunjae Kim, Hai-Woong Lee

The four Bell-type entangled coherent states, $\ensuremath{\mid}\ensuremath{\alpha}⟩\ensuremath{\mid}\ensuremath{-}\ensuremath{\alpha}⟩\ifmmode\pm\else\textpm\fi{}\ensuremath{\mid}\ensuremath{-}\ensuremath{\alpha}⟩\ensuremath{\mid}\ensuremath{\alpha}⟩$ and $\ensuremath{\mid}\ensuremath{\alpha}⟩\ensuremath{\mid}\ensuremath{\alpha}⟩\ifmmode\pm\else\textpm\fi{}\ensuremath{\mid}\ensuremath{-}\ensuremath{\alpha}⟩\ensuremath{\mid}\ensuremath{-}\ensuremath{\alpha}⟩$, can be discriminated with a high probability using only linear optical means, as long as $\ensuremath{\mid}\ensuremath{\alpha}\ensuremath{\mid}$ is not too small. Based on this observation, we propose a simple scheme to almost completely teleport a superposed coherent state. The nonunitary transformation that is required to complete the teleportation can be achieved by embedding the receiver's field state in a larger Hilbert space consisting of the field and a single atom and performing a unitary transformation on this Hilbert space.

Quantum Teleportation with a Complete Bell State Measurement

Yoon-Ho Kim, S. P. Kulik, Yanhua H. Shih

We report a quantum teleportation experiment in which nonlinear interactions are used for the Bell state measurements. The distinct feature of this experiment is that all four Bell states can be distinguished in the Bell state measurement. Teleportation of a quantum state can thus occur with certainty in principle.

Quantum teleportation with a complete Bell state measurement

Yoon-Ho Kim, S. P. Kulik, Yanhua H. Shih

Summary form only given. The idea of quantum teleportation is to utilize the nonlocal correlations between an Einstein-Podolsky-Rosen pair of particles to prepare a quantum system in some state, which is the exact replica of an arbitrary unknown state of a distant individual system. Three experiments in this direction were published recently. In this paper, we experimentally demonstrate a quantum teleportation scheme which satisfies all four of the above conditions. The input state is an arbitrary polarization state and the BSM can distinguish all four orthogonal Bell states so that the state has a 100% certainty to be teleported in principle. This is because the BSM is based on nonlinear interactions which are necessary and non-trivial physical processes for correlating the input state and the entangled EPR pair.

Scheme for teleportation of entangled states without Bell-state measurement by using one atom

Wen-Chao Qiang, Lei Zhang, Ai-Ping Zhang +1 more

We propose a scheme for approximately and conditionally teleporting an entanglement of zero- and one-photon states from a cavity with left- and right-polarized modes to another similar one, with a fidelity exceeding 99%. Instead of using the Bell-state measurement, only one atom is used in our scheme. The time spent, the success probability and the feasibility of the proposed scheme are also discussed.
