A one-way street for light

Researchers have successfully created a new one-way street for light by cooling photons to a Bose-Einstein condensate. This process causes the light to collect in optical valleys from which it can no longer return, effectively irreversibly dividing the light beam. The findings could be of interest for future quantum communication.
