Cluster State Quantum Computing
Abstract
Experimental, theoretical and numerical investigations of quantum computation using photon-based qubits were conducted to explore the Cluster State (or one-way) Quantum Computing paradigm. This report describes research on a unique type II SPDC source (Schioedtei) design that can generate up to six pairs of entangled photons per pass through the type II crystal assembly. This source is currently being used as the entangled photon source to create photon-based qubit cluster states. Under this project we developed a new detector design architecture that turns the single photon detector into a number-resolving detector by means of a novel three dimensional architecture that utilizes spatial multiplexing. We have studied the CNOT gate, as an archetypical quantum linear optical gate, and found several interesting features in the both the ideal and the realistic case of implementation with imperfect (non-unit) fidelity. We have conducted a theoretical investigation of the limitations of quantum correlations under the physically imposed constraint of no-signaling (no faster than light communication). We discuss our ongoing work of quantum algorithm development.
