Atomic clock to sync handhelds Its physics package, or atomic works, is about the size of a grain of rice, making it potentially easy to mass produce and integrate with hand-helds and other electronics. It is accurate within 25 microseconds per day, or about a second per 126 years.   |

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. |

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. |
