Recent experimental results and proposals towards implementation of quantum teleportation are discussed. It is proved that reliable ~theoretically, 100% probability of success! teleportation cannot be achieved using the methods applied in recent experiments, i.e., without quantum systems interacting with one another. Teleportation proposals involving atoms and electromagnetic cavities are revie...

We study quantum teleportation between two different types of optical qubits, one of which is “particlelike” and the other “fieldlike,” via hybrid entangled states under the effects of decoherence. We find that teleportation from particlelike to fieldlike qubits can be achieved with a higher fidelity than that in the opposite direction. However, teleportation from fieldlike to particlelike qubi...

Quantum teleportation schemes in which operations are performed before establishing the quantum channel are not constrained by resource limits set in H.K.Lo [8] and Bennett et al. [4]. We compare the standard teleportation protocol to the one proposed by Kak on the basis of the classical communication cost. Due to its unique architecture we study the problems in implementing Kak teleportation p...

Since its discovery in 1993, we witness an intensive theoretical and experimental effort centered on teleportation. Very recently it was claimed in the press that " quantum teleportation has been achieved in the laboratory " (T. Sudbery, Nature 390, 551). Here, I briefly review this research focusing on the connection to nonlo-cal measurements, and question Sudbery's statement. A philosophical ...

We study the efficiency of two-qubit mixed entangled states as resources for quantum teleportation. We first consider two maximally entangled mixed states, viz., the Werner state[1], and a class of states introduced by Munro et al. [2]. We show that the Werner state when used as teleportation channel, gives rise to better average teleportation fidelity compared to the latter class of states for...

In this work, we give a description of the process of teleportation between Alice in an inertial frame, and Rob who is in uniform acceleration with respect to Alice. The fidelity of the teleportation is reduced due to Davies-Unruh radiation in Rob's frame. In so far as teleportation is a measure of entanglement, our results suggest that quantum entanglement is degraded in noninertial frames.

We present a mathematical formulation of old teleportation protocol (original teleportation protocol introduced by Bennett et.al.) in a new fashion and study in detail the role of mixedness of the two qubit quantum channel in a teleportation protocol. We show that maximally entangled mixed state described by the density matrix of rank-4 will be useful as a two qubit teleportation channel to tel...

Using quantum teleportation a quantum state can be teleported with a certain probability. Here the probabilities for multiple teleportation are derived, i.e. for the case that a teleported quantum state is teleported again or even more than two times, for the two-dimensional case, e.g., for the two orthogonal directions of the polarization of photons. It is shown that the probability for an exa...

Teleportation is a widely implemented virtual locomotion technique that allows users to navigate beyond the confines of available tracking space with low possibility inducing reality (VR) sickness. This paper provides comprehensive overview prior research on teleportation. We report results from user studies have evaluated teleportation in comparison other methods and survey improved versions i...

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 succeeds to teleport, its fidelity, i.e. how well the input state is reproduced at the output, and by its insensitivity to cross talk, i.e. how well it rejects an input state that is not intended to teleport...
