Schrödinger's cat in action

The National Institute of Standards and Technology (NIST) strengthens U.S. economic competitiveness by developing technologies, measurement methods, and standards. NIST also works with industry to overcome technological hurdles that limit quality and innovation.

The NIST website at www.nist.gov features interesting explanations about physics discoveries with possible industrial applications. From the most recent story:

Scientists at the NIST have coaxed atoms into spinning in two opposite directions at the same time, a so-called Schrödinger “cat” state that obeys the unusual laws of quantum physics. The ambitious choreography could be useful in applications such as quantum computing. The nuclei of six entangled beryllium ions spun clockwise and counterclockwise at the same time. Entanglement, which Albert Einstein called “spooky action at a distance,” occurs when the quantum properties of two or more particles are correlated …
