Cluster states serve as the central physical resource for one-way quantum computing. We here present an experimental demonstration of the efficient cluster-state construction scheme proposed by Browne and Rudolph. In our experiment, three-photon cluster states with high purity are created from two Bell states via a qubit ``fusion'' operation, showing a strong violation of a three-particle Mermin inequality of $\ensuremath{\mid}⟨A⟩\ensuremath{\mid}=3.10\ifmmode\pm\else\textpm\fi{}0.03$.

Experimental characterization of universal one-way quantum computing

This work performs quantum process tomography to completely characterize a controlled-NOT, Hadamard and T gate all on the same compact entangled resource, making up a universal set of gates such that arbitrary quantum logic can be efficiently constructed from combinations of them.

Resource-efficient generation of linear cluster states by linear optics with postselection

We report on theoretical research in photonic cluster-state computing. Finding optimal schemes of generating non-classical photonic states is of critical importance for this field as physically

Deterministic tripartite sharing of an arbitrary single-qubit operation with the five-qubit cluster state in a given entanglement structure

A tripartite scheme for sharing a single-qubit operation on a remote target state is proposed and the underlying physical essence why the cluster state in the entanglement structure can be used to fulfill the task is revealed via deep studies.

One‐way Quantum Computation

This chapter provides an introduction to one-way quantum computation, and several of the techniques one can use to describe it, and introduces graph and cluster states and develop a notation for general single-qubit measurements.

Cluster-state quantum computing in optical fibers

A scheme for the implementation of the cluster-state model of quantum computing in optical fibers, which enables the feed-forward feature, is proposed. This scheme uses the time-bin encoding of

High-speed linear optics quantum computing using active feed-forward

It is demonstrated that, for a perfect cluster state and no photon loss, the one-way quantum computation scheme would operate with good fidelity and that the feed-forward components function with very high speed and low error for detected photons.

Generations of N-atom GHZ state and $$2^n$$2n-atom W state assisted by quantum dots in optical microcavities

Simulations show that the proposed theoretical schemes to generate entanglements among several trapped atoms with the help of quantum dots in single-side optical microcavities are faithful and available with present physical techniques.

A proof-of-principle experiment of eliminating photon-loss errors in cluster states

Quantum computation can be efficiently achieved by adopting the cluster-state model in principle, that is, first preparing multi-qubit cluster states and then performing single-qubit measurements.
