We construct a quantum circuit to produce a task-oriented partially entangled state and use it
as the quantum channel for controlled joint remote state preparation. Unlike most previous …

The process of teleport information remotely in presence of an error in the implementation of
the local operations as CNOT and Hadamard gate at the sending station is discussed …

Using a partially entangled EPR-type state as quantum channel, we investigate quantum
teleportation (QT) of a qubit state in noisy environments by solving the master equation in …

We study quantum teleportation with the resource of non-orthogonal qubit states. We first
extend the standard teleportation protocol to the case of such states. We investigate how the …

Long distance atomic teleportation (LDAT) is of prime importance in long distance quantum
communication. Scheme proposed by Bose et al.(1999) in principle enables us to have …

We study the problem of the influence of one-sided different noisy channels to the quantum
correlations decay in a symmetric bosonic system. We concentrate on one type of these …

It is proved that a qubit encoded in excited states of a V-type quantum system cannot be
perfectly transferred to the state of the cavity field mode using a single rectangular laser …

Using the two-mode two-photon Jaynes–Cummings model, entanglement transfer between
atoms and field is studied. It is found that when the field is in state constructed from the two …

Joint remote state preparation is a multiparty global quantum task in which several parties
are assigned to jointly prepare a quantum state for a remote party. Although various …

The schemes proposed by S. Bose et al [Phys. Rev. Lett. 83, 5158 (1999)] and others for
long distance atomic teleportation using cavity decay, gives message state dependent …
