(Phys.org) —The ability to guide, bend and focus light at the nanoscale is a highly sought-after goal in the field of nano-optics. Precise and efficient light control has direct applications in solar cells, holography, ...
(Phys.org)—Biological systems are characterized by a form of molecular recycling – and proteins do not escape this fate. In particular, unneeded or damaged proteins biochemically marked for destruction undergo controlled ...
One of the many promising applications of quantum mechanics in the information sciences is quantum key distribution (QKD), in which the counterintuitive behavior of quantum particles guarantees that no one can eavesdrop on ...
