Strong Photon-Photon Interaction Created in Fiber

Facebook X LinkedIn Email
VIENNA, Nov. 3, 2014 — An ultrathin glass fiber system could facilitate the interaction of pairs of photons. The technique, developed by a team at the Vienna University of Technology, could become an important tool in furthering quantum computing. To establish the photon-photon interaction, an ultrathin glass fiber was coupled with a tiny bottle-like light resonator, allowing light to partially enter it, move in circles and then return to the fiber. This detour through the resonator led to the phase of the photon being inverted, according to the researchers, meaning a wave crest appeared where a wave...Read full article
