Scalable quantum computing and communication requires the protection of quantum
information from the detrimental effects of decoherence and noise. Previous work tackling …

In this book chapter, we provide a tutorial introduction to one‐way quantum computation and
many of the techniques one can use to understand it. The techniques which are described …

We experimentally demonstrate an optical controlled-not (cnot) gate with arbitrary single
inputs based on a 4-photon 6-qubit cluster state entangled both in polarization and spatial …

Six-qubit cluster states built on the simultaneous entanglement of two photons in three
independent degrees of freedom, that is, polarization and a double longitudinal momentum …

We present schemes to prepare two-dimensional cluster states [HJ Briegel and R.
Raussendorf, Phys. Rev. Lett. 86, 910 (2001)] with atomic ions confined in a microstructured …

We propose two schemes that generate four-photon cluster states based on quantum dot
microcavity coupling systems. In the first scheme, the four-photon cluster state is generated …

The theoretical and experimental investigation results of the generation of the polarization-
entangled photon pairs operating at visible wavelengths are reported. The generation of …

We propose and demonstrate the scaling up of photonic graph states through path qubit
fusion. Two path qubits from separate two-photon four-qubit states are fused to generate a …

We introduce and experimentally demonstrate a method for realising a quantum channel
using the measurement-based model. Using a photonic setup and modifying the basis of …

In this paper, we use a quantum channel that is the product of two states, the four-qubit
cluster state and the three-qubit partially entangled state. This quantum channel is used as a …
