A posteriori teleportation

  title={A posteriori teleportation},
  author={Samuel L. Braunstein and Harry J. Kimble},
The article by Bouwmeester et al. on experimental quantum teleportation constitutes an important advance in the burgeoning field of quantum information. The experiment was motivated by the proposal of Bennett et al. in which an unknown quantum state is ‘teleported’ by Alice to Bob. As illustrated in Fig. 1, in the implementation of this procedure by Bouwmeester et al., an input quantum state is ‘disembodied’ into quantum and classical components, as in the original protocol. However, in… 

The Innsbruck quantum teleportation experimental scheme can be modified to the unconditional one

We show that the Innsbruck quantum teleportation experiment(Bouwmeester D et al, Nature 390, 575(1997)) can be modified by using the polarized beam splitter. In this modified scheme, Bob does not

Experimental Realization of Continuous Variable Teleportation

In quantum teleportation, Alice and Bob neatly circumvent constraints that would otherwise be imposed on Alice's state measurement and Bob's state generation, and are thereby able to reconstruct the original state at Bob’s place.

Experimental realization of freely propagating teleported qubits

The basic idea is to suppress unwanted coincidence detection events by providing the photon to be teleported much less frequently than the auxiliary entangled pair, and the experimental fidelity of the procedure surpasses the theoretical limit required for the implementation of quantum repeaters.

Teleportation of entangled states

Teleportation of some pure entangled states of discrete and continuous variables is considered using a multi-particle quantum channel; particularly a Greenberger-Horne-Zeilinger channel. Both the

Unconditional quantum teleportation

The first realization of unconditional quantum teleportation where every state entering the device is actually teleported is realized, using squeezed-state entanglement.

A single quantum cannot be teleported

Due to the Heisemberg uncertainty principle, it is impossible to design a procedure which permits perfect cloning of an arbitrary, unknown "qubit" (the spin or polarization state of a single quantum

Criteria for continuous-variable quantum teleportation

Abstract We derive an experimentally testable criterion for the teleportation of quantum states of continuous variables. This criterion is especially relevant to the recent experiment of Furusawa et

Quantum teleportation scheme by selecting one of multiple output ports

The scheme of quantum teleportation, where Bob has multiple output ports and obtains the teleported state by simply selecting one of the $N$ ports, is thoroughly studied and the optimal protocols can achieve the perfect teleportation in the asymptotic limit of $N\ensuremath{\rightarrow}\ensure math{\infty}$.

High-fidelity teleportation of independent qubits

Abstract Quantum teleportation is one of the essential primitives of quantum communication. We suggest that any quantum teleportation scheme can be characterized by its efficiency, i.e. how often it

Optical hybrid quantum teleportation and its applications

This approach enabled the first realization of deterministic quantum teleportation of photonic qubits without post-selection, and is now aiming at universal, scalable, and fault-tolerant quantum computing based on these hybrid technologies.



Experimental quantum teleportation

It is shown that during teleportation, one of a pair of entangled photons are subjected to a measurement such that the second photon of the entangled pair acquires the polarization of the initial photon.

Teleporting an unknown quantum state via dual classical and Einstein-Podolsky-Rosen channels.

An unknown quantum state \ensuremath{\Vert}\ensuremath{\varphi}〉 can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical Einstein-Podolsky-Rosen
