Product Description
NMR quantum computing with qubit systems represented by nuclear spins with I=1/2 of small moleculesin liquids has led to the most successful experimental quantum information processors so far. We use the quadrupolar spin-3/2 sodium nuclei of a NaNO3 single crystal as a virtual two-qubit system. The large quadrupolar coupling in comparison with the environmental interactions and the usage ofstrongly modulating pulses allow us to manipulate the system fast enough and at the same timekeeping the decoherence reasonably slow. The experimental challenge is to characterize thecalculation behavior of the quantum processor by process tomography which is here adapted tothe quadrupolar spin system. The results of a selection of quantum gates and algorithms arepresented as well as a detailed analysis of the decoherence behavior of our quantum processor. |
