Cluster state generation with ageing qubits
Pieter Kok · 2013
Cluster states for measurement-based quantum computing can be created with entangling operations of arbitrary low success probability. This will place a lower bound on the minimum lifetime of the qubits used in the implementation. Here, we present a simple scaling argument for the T2time of the qubits for various cluster state geometries. The results suggest that the required T2times are not unrealistic for the practical implementation of universal quantum computing with cluster states.
