Abstract

Recently quantum computation has raised much interest because it may be able to solve some important problems that are not solvable by classical computation.1 One possible quantum logical element is a two-level system controlled by optical pulses.2 A π-pulse field has a function of NOT operation as it flips the state of the atom, and a π/2 pulse has a function of √NOT operation as two successive operations of this gives a single NOT operation. A single √NOT operation creates a coherent superposition of the upper and lower levels of the atom, which is a key operation in quantum computation.
