摘要：

We demonstrate the implementation of Grover's quantum search algorithm on a liquid state nuclear magnetic resonance quantum computer using essentially pure states. This was achieved using a two qubit device where the initial state is an essentially pure (e = 1.06 +/- 0.04) singlet nuclear spin state of a pair of H-1 nuclei arising from a chemical reaction involving para-hydrogen. We have implemented Grover's search to find one of four inputs which satisfies a function. (C) 2004 Elsevier B.V. All rights reserved.
