Light clock promises finer time Researchers have made a prototype atomic clock that divides time on optical radiation, rather than microwave radiation. Such clocks could eventually improve global positioning systems, make space exploration more accurate, and more accurately test the laws of physics. mark for My Articles similar articles

Quantum timepiece ticks the right boxes In a remarkable feat of quantum horology, scientists in the US have created a clock that derives its timing mechanism from nothing more complicated than the mass of an atom. The new clock could prove to be a new way to make highly accurate measurements of atomic mass. mark for My Articles similar articles

Laser made from single atom The simplest possible laser -- a single atom -- has been on the drawing board for decades. Researchers have finally achieved the extremely precise control needed to make a laser from just one atom. The first demonstration of a single-atom laser showed that it's a different animal -- it produces quantum light. mark for My Articles similar articles
