Experimental realization of a fetching algorithm in a 7 qubit NMR
quantum computer
Gui Lu Long, Li Xiao
abstract: Searching for marked items from an unsorted database is an important
scientific problem and a benchmark for computing devices as well. Using a
7-qubit liquid NMR quantum computer, we have demonstrated successfully an
hybrid quantum fetching algorithm that finds marked items using only a single
query. The essential idea is the operation of quantum computers in parallel. We
gave the detailed pulse sequence for coherent control of the 7 qubits. The
pulse sequence demonstrated here is not only useful for ensemble quantum
computation, but also can be regarded as a general purpose control-gate which
is useful for experimental design of quantum algorithms and general quantum
information processing task in other quantum computer schemes. A generalization
of the algorithm that is scalable to arbitrary qubit number is also provided.
