โฆ Synopsis
Experimental verification is presented of recent theoretical predictions of spin inversion schemes that rely on temporal interferences during the sweep. The experiments were carried out using liquid state NMR. It is shown how under non-adiabatic conditions, both complete inversion and complete non-inversion can be achieved, due to slight but easily reproducible alteration of one control parameter. The implications of this scheme for quantum computing are discussed.
