Process Tomography of a nuclear quadrupolar spin quantum information processor — •Hermann Kampermann — Universität Düsseldorf
In the present work the first virtual 2 qubit solid state NMR quantum processor, using the spin-3/2 Na nuclei of a NaNO3 single crystal, is presented. Methods from liquid NMR, like strongly modulating pulses, are adopted to the quadrupolar spin system to implement efficient unitary operations and to generate pseudo pure states. The procedure of quantum process tomography was developed for the quadrupolar spin system, which is used to characterize quantum algorithms and the decoherence process.
