Optical quantum computation using cluster states

1 min read

Introduces a photonic path to cluster-state measurement-based quantum computation by combining linear optics with pre-entangled cluster resources and adaptive measurements.

Abstract

We propose an approach to optical quantum computation in which a deterministic entangling quantum gate may be performed using, on average, a few hundred coherently interacting optical elements (beamsplitters, phase shifters, single photon sources, and photodetectors with feedforward). This scheme combines ideas from the optical quantum computing proposal of Knill, Laflamme and Milburn, and the abstract cluster-state model of quantum computation proposed by Raussendorf and Briegel.

Key Findings

  • Establishes a concrete optical implementation route for cluster-state MBQC.
  • Clarifies feed-forward and resource overhead tradeoffs in photonic MBQC.
