Abstract

A growing appreciation among researchers is the use of quadrupolar nuclei with spin >1/2 as a suitable candidate for quantum information processing. Such systems have multiple qubits per nuclei and large quadrupolar couplings, resulting in well separated lines in the spectrum. Preparation of pseudopure states and implementation of logic gates have been demonstrated in these systems. Two-qubit quantum algorithms have also been implemented in spin-3/2 systems. In this letter we report implementation of three-qubit Deutsch-Jozsa algorithm [Proc. R. Soc. London, Ser. A 693, 553 (1992)] in a spin-7/2 system of $^{133}Cs$ nucleus oriented in a liquid crystalline matrix.
