Photon 'time bins' and signal stability show promise for practical quantum communication via fiber optics by Lavinia Meier-Ewert, Leibniz Institute of Photonic Technology edited by Lisa Lock, reviewed ...

The encryption protecting communications against criminal and nation-state snooping is under threat. As private industry and governments get closer to building useful quantum computers, the algorithms ...

One approach significantly increases the amount of information that can be encoded in a single photon; the other improves the stability of the quantum signal over long distances. Both methods rely on ...
