Computers set for quantum leap

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 today’s 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.

An early application will be to investigate and design complex molecules, such as new drugs and other materials, that cannot be simulated with ordinary computers. More general consumer applications should follow. the rest image
