Foundational measurement-based model introducing cluster states as a universal substrate where computation proceeds via adaptive single-particle measurements.

Abstract

We propose a different model of a scalable quantum computer in which the entire resource for the quantum computation is provided initially in the form of a specific entangled state (a cluster state) of a large number of qubits. Information is then written onto the cluster, processed, and read out from the cluster by one-particle measurements only.

Key Findings

  • Establishes the core MBQC / one-way computation paradigm.
  • Provides the conceptual basis later specialized to photonic cluster-state architectures.
