Phys. Rev. A 72, 062309 (2005) [5 pages]Fast SWAP gate by adiabatic passageReceived 26 January 2005; revised 20 May 2005; published 6 December 2005 We present a process for the construction of a SWAP gate which does not require a composition of elementary gates from a universal set. We propose to employ direct techniques adapted to the preparation of this specific gate. The mechanism, based on adiabatic passage, constitutes a decoherence-free method in the sense that spontaneous emission and cavity damping are avoided. © 2005 The American Physical Society URL:
