University of Toronto physicists lay the groundwork for cooler, faster computing

University of Toronto quantum optics researchers Sajeev John and Xun Ma have discovered new behaviours 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 a recent issue of Physical Review Letters.
