Photonic Computers: Faster And Cooler Than Their Electronic Counterparts
University of Toronto quantum optics researchers have discovered new behaviors of light within photonic crystals that could lead to faster optical information processing and compact computers that don't overheat. "We discovered that by sculpting a unique artificial vacuum inside a photonic crystal, we can completely control the electronic state of artificial atoms within the vacuum," says Ma, a PhD student under John's supervision and lead author of a study published in the Dec. 4 issue of Physical Review Letters. "This discovery can enable photonic computers that are more than a hundred times faster than their electronic counterparts, without heat dissipation issues and other bottlenecks currently faced by electronic computing." read more
