摘要
We demonstrate the implementation of a quantum algorithm on a liquid-state NMR quantum computer using almost pure states. This was achieved using a two-qubit device where the initial state is an almost pure singlet nuclear spin state of a pair of H-1 nuclei arising from a chemical reaction involving parahydrogen. We have implemented Deutsch's algorithm for distinguishing between constant and balanced functions with a single query.
