Chinese team entangles eight photons, breaking record
In a game of one-upmanship, a Chinese team of physicists has figured out how to entangle eight photons simultaneously and to observe them in action; the previous record was six. In a paper published in arXiv, the team from t ...

Shining a light around corners: Scientists explore a new method for curving 'Airy' light beams
We learned in science class that light beams travel in straight lines and spread through a process known as diffraction -- and they can't go around corners. But now researchers at Tel Aviv University are investigating new ...
