Abstract

The quantum teleportation of displaced Fock states is studied. The teleportation of the oscillations of their photon distributions is derived in terms of the compression parameter of the correlated EPR states of the quantum channel.

Teleportation of displaced Fock states: Fidelity and their teleported photon number distributions

William Quintero, Celso L. Ladera

We consider the teleportation of displaced Fock states which are highly non-classical states of the quantized electromagnetic field which have a set of remarkable quantum properties that include the peculiar oscillations of their photon number distributions. We use the transfer operator formalism to show that the quantum teleportation of a DFS renders a finite superposition of orthonormal DFS's and find its explicit mathematical expression in terms of the compression parameter of the correlated EPR states of the quantum channel. The expression for a teleported Fock state is also derived as a particular case of DFS's teleportation. We finally apply these results to study the fidelity of the teleportation of DFS's and the teleportation of their photon number statistics.

Quantum Teleportation of One-Photon and Two-Photon Superposition States

Ying Li

One-photon and two-photon superposition states are the fundamental quantum states, which have shown interesting features, such as squeezing and anti-bunching. In this paper we discuss the quantum teleportation of such quantum states with the continuous-wave EPR states. Fidelity as a function of EPR correlation is obtained. We also compared the results with Fock state and coherent state teleportation.

Quantum teleportation of one- and two-photon superposition states

Ying Li, Tiancai Zhang, Zhang Jun-Xiang +1 more

Quantum teleportation of one- and two-photon superposition states based on EPR entanglement of continuous-wave two-mode squeezed state is discussed. The fidelities of teleportation are deduced for two different input quantum states. The dependence of the fidelity on the parameters of EPR entanglement and the gain of the classical channels are shown numerically. Comparing with the teleportation of Fock state and coherent state, it is pointed out that for given EPR entanglement and classical gain, the higher the nonclassicality of the input state, the lower the accessible fidelity of teleportation.

Quantum Teleportation of an Arbitrary N-qubit State via EPR Channels

Bo Zhang, Xingtong Liu, Jian Wang +1 more

This paper demonstrates that an arbitrary -qubit state can be faithfully and deterministically teleported from Alice to Bob via pairs of EPR channels. The analytical expression of the reconstruct criterion is derived explicitly in the most general case, with a strict proof through mathematical induction method.

Teleportation-Induced Correlated Quantum Channels

Filippo Caruso, Vittorio Giovannetti, G. Massimo Palma

Quantum teleportation of an n-qubit state performed using as an entangled resource a general bipartite state of 2n qubits instead of n Bell states is equivalent to a correlated Pauli channel. This yields a new characterization of such channels in terms of many-body correlation functions of the teleporting media. It provides a relatively simple method for determining whether a correlated quantum channel is able to reliably convey quantum messages by studying the entanglement properties of the teleportation mediating system. Our model is then generalized to the continuous-variable case.
