文摘A quantum algorithm for Deutsch-Jozsa problem was implemented by nuclear magnetic resonance of benzene with heteronuclear decoupling during the readout period. It was demonstrated that decoupling can not only remove the undesired long-range couplings but also save the frequency space taken up by nuclear spins, which was expected to be important when scaling to large systems, and also to enhance the signal-to-noise ratio.
