Abstract

We demonstrate experimentally the usefulness of selective pulses in NMR to perform quantum computation.Three different techniques based on selective pulse excitations have been proposed to prepare a spin system in a pseudopure state. We describe the design of ‘‘portmanteau’’ gates using the selective manipulation of level populations. A selective pulse implementation of the Deutsch-Jozsa algorithm for two and three-qubit quantum computers is demonstrated.
