GLASGOW, Scotland, & LONDON, May 10, 2013 — A microfabricated chip that produces ultracold atoms could lead to portable, ultraprecise clocks and quantum sensors. Many of the most accurate measurement devices, including atomic clocks, work by observing how atoms transfer between individual quantum states. The highest precision is...Read full articleRelated content from Photonics MediaARTICLESOptical Clock Uses Laser Tweezers to Manipulate AtomsJILA physicists have demonstrated a new atomic clock design that uses laser tweezers to trap, control, and isolate atoms.
