Nuclear magnetic resonance quantum logic gates using quadrupolar nuclei

Anatoly K. Khitrin, B. M. Fung

The use of nuclei with spin >1/2 and quadrupolar splitting of the spin energy levels has certain advantages over systems of interacting spins 1/2 for building quantum logic gates. Experimental demonstration has been made using 23Na (spin 3/2) NMR in a lyotropic liquid crystal system. The pulse sequences for establishing effective pure quantum states are given, and the resulting NMR spectra are presented.

The relationship between ensemble quantum computing logical gates and NMR pulse sequence engineering exemplified by the SWAP operation

Thomas Schulte-Herbr�ggen, Ole W. Sørensen

This paper describes how to derive nuclear magnetic resonance (NMR) pulse sequences suitable as ensemble quantum computing logical gates by known systematic tools for design of pulse sequences in NMR spectroscopy. This is in contrast to the current trend of developing NMR pulse sequences for ensemble quantum computing independent of established NMR spectroscopic technology, although many of the pertinent spin manipulations are already known in NMR spectroscopy. The SWAP operation is discussed in detail and one version is only (2J)−1long, which compares favorably with 3(2J)−1 in a recent implementation (Linden N, Barjat H, Kupce E, Freeman R. Chem Phys Lett 1999; 307:198–204). Alternatively, the number of π pulses can be reduced in that sequence. © 2000 John Wiley & Sons, Inc.
