Austrian and Chinese scientists have succeeded in teleporting three-dimensional quantum states for the first time. High-dimensional teleportation could play an important role in future quantum computers.  An efficient light-matter interface might constitute the foundation of quantum communication. However, certain structures that are formed during the growth process interfere with the signal.  Physicists at C2N have demonstrated for the first time the direct generation of light in a state that is simultaneously a single photon, two photons, and no photon at all.  A team of researchers from Xiamen University, the University of Ottawa and the University of Rochester has shown that it is possible to entangle photons with correlations between their radial and momentum states.  In a new study, researchers demonstrate creative tactics to get rid of loopholes that have long confounded tests of quantum mechanics.  This is a very interesting quantum phenomenon called "magnon crystallization," in which the magnons are said to be in a "frustrated" state.  In a new paper, have proposed the first practical protocol for anonymous communication in quantum networks.  Researchers from QuTech have achieved a world's first in quantum internet technology.  The achievement represents a major step towards a "quantum internet," in which future computers can rapidly and securely send and receive quantum information.  Scientists have used precisely tuned pulses of laser light to film the ultrafast rotation of a molecule.
