Cluster-state generation with aging qubits
Joshua M. Waddington, Joshua A. Kettlewell, Pieter Kok · Physical Review A · 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 ${T}_{2}$ time of the qubits for various cluster-state geometries, and we estimate the size of the qubit reservoir that is needed for the creation of miniclusters.
