The presence or absence of a single exciton in the dot provides a qubit that we control with femtosecond time resolution. We combine a set of quantum operations to realize the single-qubit Deutsch-Jozsa algorithm. The results show the feasibility of single qubit quantum logic in a semiconductor quantum dot using ultrafast optical control.", "revisions": [ { "version": "v2", "updated": "2004-03-18T18:13:48.000Z" } ], "analyses": { "keywords": [ "qubit deutsch-jozsa algorithm", "experimental realization", "perform quantum interference experiments", "single qubit quantum logic", "single self-assembled semiconductor quantum dot" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
