Noisy One-Way Quantum Computations: The Role of Correlations
arXiv:1007.2165 · doi:10.1103/PhysRevA.84.022324
Abstract
A scheme to evaluate computation fidelities within the one-way model is developed and explored to understand the role of correlations in the quality of noisy quantum computations. The formalism is promptly applied to many computation instances, and unveils that a higher amount of entanglement in the noisy resource state does not necessarily imply a better computation.
