But experts say the achievement is still significant as a demonstration of the future promise of quantum computing. How is a quantum computer different from a conventional computer? The potential promise of quantum computing is that a quantum computer does something that we could never do with ordinary digital computers. Google research scientists Amit Vainsencher, foreground, and Ofer Naaman assemble and test microwave cables to control qubits at the extremely low temperatures required for quantum computing. Based on our current understanding, I think quantum computers will have very specialized applications.
