Method of quantum computation with ``hot'' trapped ions
Sara Schneider, Daniel F. V. James, Gerard J. Milburn
Abstract
We present a novel method of performing quantum logic gates in trapped ion quantum computers which does not require the ions to be cooled down to their vibrational center of mass (CM) mode ground state. Our scheme employs adiabatic passages and the conditional phase shift first investigated by D'Helon and Milburn (C.~D'Helon and G.J.~Milburn, Phys. Rev. A 54, 5141 (1996)).
