Abstract

The highly entangled four qubit cluster state can be used to perform an arbitrary single logical qubit rotation via the techniques of measurement-based quantum computation. In this paper, we explore the relationship between the entanglement in the cluster state and the ability of the state to accurately perform the desired logical rotation. This has important experimental ramifications as realistic cluster state experiments will always be subject to decoherence. We also note the exhibition of entanglement sudden death (ESD) and ask how severely its onset affects the utilization of the cluster state as a means of implementing the arbitrary single logical qubit rotation.
