Researchers from Edinburgh and Manchester University have created a molecular machine that could be used to develop quantum computers for making "intricate calculations" far more quickly than current supercomputers. Essentially, the reseachers relied on molecular scale technology instead of silicon chips; more specifically, they achieved the so-called breakthrough by "combining tiny magnets with molecular machines that can shuttle between two locations without the use of external force." Not surprisingly, there's still more work to be done, with Professor David Leigh of Edinburgh University noting that "the major challenges we face now are to bring many of these qubits together to build a device that could perform calculations, and to discover how to communicate between them."
