JILA and NIST scientists are hot on the trail of understanding quantum correlations (or entanglement) among groups of quantum particles such as atoms or ions. Such particles are the building blocks of larger and larger chunks of matter that make up the everyday world. Interestingly, correlated atoms and ions exhibit exotic behaviors and accomplish tasks that are impossible for noninteracting particles. Therefore, understanding how entanglement is generated in those systems is not only central to comprehending our world, but also advancing technology.

The development of a new experimental method to measure quantum correlations between particles was the focus of a recent collaboration between Ana Maria Rey’s theory group at JILA and NIST experimentalist John Bollinger’s group. The two groups worked together on an experimental study of quantum correlations in a trapped-ion magnet consisting of ~100 beryllium (Be+) ions. The Rey group’s theory predicted that the experimenters could measure the build up of entanglement caused by the interactions between the ions by illuminating the ions with lasers that allow the ions to interact going forwards and then backwards...
