A new photonic chip that works on light rather than electricity has been built by an international research team, paving the way for the production of ultra-fast quantum computers with capabilities far beyond todays devices. Future quantum computers will, for example, be able to pull important information out of the biggest databases almost instantaneously. As the amount of electronic data stored worldwide grows exponentially, the technology will make it easier for people to search with precision for what they want. Jeremy OBrien, director of the UKs Centre for Quantum Photonics, who led the project, said many people in the field had believed a functional quantum computer would not be a reality for at least 25 years. However, we can say with real confidence that, using our new technique, a quantum computer could, within five years, be performing calculations that are outside the capabilities of conventional computers, he told the British Science Festival, as he presented the research. The immense promise of quantum computing has led governments and companies worldwide to invest hundreds of millions of dollars in the field. Big spenders, including the US defence and intelligence agencies concerned with the national security issues, and governments ... see quantum electronics as the foundation for IT industries in the mid-21st century.
