The hype that has been building around quantum computing, a potentially revolutionary technology that has been a dream of physicists and computer scientists for 35 years, is about to get a big boost.
Two scientific milestones are expected to be announced in the coming weeks by two of the world’s biggest technology companies that will highlight the rapid advances now being made in the field. But whether they also point to useful commercial applications in the near term is another matter.
Some of the leading companies in the field say quantum machines, harnessing the properties of quantum mechanics to greatly speed up computation, will have important practical applications within five years — far earlier than once thought.
