Blog post: ajb: A new optical quantum network device

Researchers at the California Institute of Technology, Hewlett Packard Laboratories and University of Washington have a "proof-of-concept" device that could pave the way for on-chip optical quantum networks [1]. The device is etched in a diamond membrane that was around 300 nanometres thick.

In an optical quantum network, information is carried by photons, as opposed to electrons in more standard devices. The potentials for quantum computing are huge, computers could be millions of times faster at performing certain calculations than they are today.
