Resource-efficient linear optical quantum computation

1 min read

Develops a resource-efficient linear-optical architecture that explicitly uses the cluster-state measurement-based model and fusion-style operations.

Abstract

We introduce a scheme for linear optics quantum computation, that makes no use of teleported gates, and requires stable interferometry over only the coherence length of the photons. We follow the cluster-state measurement based quantum computational approach, and show how cluster states may be efficiently generated from pairs of maximally polarization entangled photons using linear optical elements.

Key Findings

  • Demonstrates practical cluster-state construction primitives in linear optics.
  • Improves resource efficiency versus earlier gate-teleportation-heavy approaches.
