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 obtained with long observation times, often using slow-moving ultracold atoms prepared in a large apparatus. A microfabricated grating transforms a single incoming laser beam into a light field specially tailored for trapping and cooling atoms.
