Physicists achieve longer distance quantum teleportation

Physicists in Switzerland said today they had succeeded in teleporting the quantum state of a photon to a crystal, in which information transited from light to matter, over a record distance of 25 kilometres.
The experiment, conducted over optical fibre at the University of Geneva, beat the team's previous record in 2003 of six kilometres.

Researchers invent 'meta mirror' to help advance nonlinear optical systems

Researchers at the Cockrell School of Engineering at The University of Texas at Austin have created a new nonlinear metasurface, or meta mirror, that could one day enable the 

miniaturization of laser systems. The invention, called a "nonlinear mirror" by the researchers, could help advance nonlinear laser systems that are used for chemical sensing, explosives detection, biomedical research and potentially many other applications. The researchers' study will be published in the July 3 issue of Nature.
