Abstract

We demonstrate quantum teleportation of a coherent state as cluster computation using a four-mode linear cluster state. This is the first example of realization of cluster computation in continuous-variable systems.

Generation of Four-Mode Continuous-Variable Cluster States

Cluster states are sufficient resources for realizing quantum computation. Their implementations can be achieved via either discrete‐variable systems (especially qubit systems) or continuous‐variable systems. Here we report on the experimental generation of an important example of a continuous‐variable cluster state, a four‐mode linear cluster state.

Continuous-variable Gaussian cluster states are a potential resource for universal quantum computation. Here we report on the optical generation and theoretical verification of three different kinds of four-mode continuous variable cluster states.

Examples of Gaussian cluster computation

Peter van Loock

Simple examples that illustrate the principles of one-way quantum computation using Gaussian continuous-variable cluster states are given. In these examples, only single-mode evolutions, realizable via linear clusters, are considered. In particular, one can focus on Gaussian single-mode transformations performed through the cluster state. These examples highlight the differences between cluster-based schemes and protocols in which special quantum states are prepared off-line and then used as a resource for the on-line computation.

Bidirectional quantum teleportation in continuous variables

E. A. Nesterova, S. B. Korolev

Abstract We propose a bidirectional quantum teleportation (BQT) protocol in continuous variables. We use a cluster state in continuous variables as the main resource to realize this protocol. In the paper, we obtain a family of configurations of cluster states in continuous variables that can be used to realize the BQT protocol. From the whole family of configurations, we have chosen those that realize the protocol with the smallest possible error.

Quantum Teleportation with Linear Cluster-class States

钟 锋 ZHONG Feng, 于立志 YU Li-zhi, 李春树 LI Chun-shu

A scheme for teleportation of an arbitrary two-qubit state using a four-qubit linear cluster-class state is proposed.Quantum teleportation can be successfully realized with a certain probability if the receiver can adopt an appropriate collective unitary transformation after receiving the sender's Bell-state measurement information.The scheme is more practical than previous ones using maximally entangled states as the quantum channel.In addition,an important conclusion is obtained from the above scheme that a maximally four-qubit entangled state(cluster state)is extracted from a single copy of the cluster-class state with the same probability as the teleportation.
