Phys. Rev. A 65, 054301 (2002) [4 pages]Experimental realization of a target-accepting quantum search by NMRReceived 21 June 2001; revised 12 November 2001; published 24 April 2002 With a three-bit nuclear magnetic resonance quantum computer, we have experimentally realized a quantum search algorithm that can take a desired function value (or target) t as its input and give the corresponding function argument x0 such that f(x0)=t as a result. The function value is not retrieved from an existing table, but evaluated by the search algorithm in the manner of a typical algorithmic search. A single-query version of the quantum search algorithm is used to search for one of two function arguments. © 2002 The American Physical Society URL:
