英文摘要: A generalized quantum search algorithm, where phase inversions for the marked state and the prepared state are replaced by pi /2 phase rotations, is realized in a 2-qubit NMR heteronuclear system. The quantum algorithm searches a marked state with a smaller step compared to standard Grover algorithm. Phase matching requirement in quantum searching is demonstrated by comparing it with another generalized algorithm where the two phase rotations are pi /2 and 3 pi /2, respectively. Pulse sequences which include non-90 degrees pulses are given. (C) 2001 Elsevier Science B.V. All rights reserved.
