Quantum logical gates with linear quadripartite cluster states of continuous variables
Aihong Tan, Changde Xie, Kunchi Peng · Physical Review A · 2009
The concrete schemes to realize three types of basic quantum logical gates using linear quadripartite cluster states of optical continuous variables are proposed. The influences of noises and finite squeezing on the computation precision are analyzed in terms of the fidelity of propagated quantum information through the continuous variable cluster states. The proposed schemes provide direct references for the design of experimental systems implementing quantum computation with the cluster entanglement of amplitude and phase quadratures of light.
