Experimental realization of a fetching algorithm in a 7-qubit NMR spin Liouville space computer

Using a 7-qubit spin Liouville space computer, we have demonstrated successfully a fetching algorithm that finds marked items using only a single query. The essential idea is the operation of quantum computers in classical parallel. We gave the detailed pulse sequence for coherent control of the 7 qubits. A generalization of the pulse sequences for arbitrary qubit number is also provided.
