Fast SWAP gate by adiabatic passage
Nicolas Sangouard, X. Lacour, S. Guérin, Hans Rudolf Jauslin · Physical Review A · 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.
