Title: Implementation of a two-qubit controlled-rotation gate based on unconventional geometric phase with a constant gating time
Author: Yabu-Uti, BFC
Roversi, JA
Abstract: We propose an alternative scheme to implement a two-qubit controlled-R (rotation) gate in the hybrid atom-CCA (coupled cavities array) system. Our scheme results in a constant gating time and, with an adjustable qubit-bus coupling (atom-resonator), one can specify a particular rotation R on the target qubit. We believe that this proposal may open promising perspectives for networking quantum information processors and implementing distributed and scalable quantum computation. (C) 2011 Elsevier B.V.
