Abstract

A Periodic Cluster State Generator (PCSG) consisting of a monolithic integrated waveguide device that employs four wave mixing, an array of probabilistic Photon Guns, single mode Sequential Entanglers and an array of controllable entangling gates between modes to create arbitrary size and shape cluster states with several constraints. The cluster state is assumed linear or square lattice. Only nearest neighbor qubits are entangled. Such a cluster state resource has been proven to be able to perform universal quantum computing if the initial state is large enough.

First claim

What is claimed is:

1. A photonic cluster state generator, comprising
an optical divider stage having an input into which photons from a photon source are applied, and a plurality of optical divider outputs among which said photons are evenly divided and output;
a like plurality of polarization and delay stages for synchronizing said photons in time;
a like plurality of first entanglement stages for creating entangled chains of said synchronized photons,
wherein each of said…
