Phys. Rev. A 64, 022310 (2001) [5 pages]Universal quantum computation by holonomic and nonlocal gates with imperfectionsReceived 12 September 2000; published 12 July 2001 We present a nonlocal construction of universal gates by means of holonomic (geometric) quantum teleportation. The effect of the errors from imperfect control of the classical parameters, the looping variation of which builds up holonomic gates, is investigated. Additionally, the influence of quantum decoherence on holonomic teleportation used as a computational primitive is studied. Advantages of the holonomic implementation with respect to control errors and dissipation are presented. © 2001 The American Physical Society URL:
