The geometric phases are controlled by three laser fields where pulse shapes, relative field strength and phases can be controlled. We present a robust set of universal gates for quantum computing based on these geometric phases: a one-qubit phase gate, a Hadamard gate and a two-qubit phase gate.", "revisions": [ { "version": "v1", "updated": "2007-01-31T12:13:41.000Z" } ], "analyses": { "keywords": [ "stimulated raman adiabatic passage", "geometric phase gates", "tripod systems", "generate purely geometric phase changes", "one-qubit phase gate" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
