Coupling to the environment typically suppresses quantum properties of physical systems via decoherence mechanisms. This is one main obstacles in practical implementations protocols. In this work we show how effects can be reversed/suppressed during teleportation a network scenario. Treating quantumly, that under general pure dephasing coupling, performing second step probabilistically reverse ...

The process of teleportation of a completely unknown one-particle state of a free relativistic quantum field is considered. In contrast to the non-relativistic quantum mechanics, the telepor-tation of an unknown state of the quantum field cannot be in principle described in terms of a measurement in a tensor product of two Hilbert spaces to which the unknown state and the state of the EPR-pair ...

The possibility of teleportation is by sure the most interesting consequence of quantum non-separability. So far, however, teleportation schemes have been formulated by use of state vectors and considering individual entities only. In the present article the feasibility of teleportation is examined on the basis of the rigorous ensemble interpretation of quantum mechanics (not to be confused wit...

The role of the off-diagonal density matrix elements of the entangled pair is investigated in quantum teleportation of a qubit. The dependence between them and the off-diagonal elements of the teleported density matrix is shown to be linear. In this way the ideal quantum teleportation is related to an entirely classical communication protocol: the one-time pad cypher. The latter can be regarded...

I show that an experimental technique used in nuclear physics may be successfully applied to quantum teleportation (QT) of spin states of massive matter. A new non-local physical effect the 'quantum-teleportation-effect' is discovered for the nuclear polarization measurement. Enhancement of the neutron polarization is expected in the proposed experiment for QT that discriminates only one of the...

The three results on the PageRank vector are preliminary but shed light on the eigenstructure of a PageRank modified Markov chain and what happens when changing the teleportation parameter in the PageRank model. Computations with the derivative of the PageRank vector with respect to the teleportation parameter show predictive ability and identify an interesting set of pages from Wikipedia.

We extend the scheme of quantum teleportation by walks introduced Wang et al. (2017). First, we introduce mathematical definition accomplishment this extended scheme. Secondly, show a useful necessary and sufficient condition that is accomplished rigorously. Our result classifies parameters setting for teleportation.

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 i...
