Jürgen Appel started his doctoral work on quantum optics at the University of Konstanz, Germany, in the group of Prof. A. Lvovsky, investigating quantum interaction between light and atoms by electromagnetically induced transparency (EIT). In 2004, the group moved to Calgary, Canada, and set up new laboratories at the Institute for Quantum Information Science. In June 2007, he received his Ph.D. in physics for work on producing continuous variable nonclassical light states and storing them in an EIT quantum memory. Dr. Appel is currently a postdoctoral researcher at the Niels Bohr Institute, Copenhagen, Denmark, in the group of Prof. Eugene Polzik, working on quantum nondemolition measurements, spin-squeezing on the cesium clock transition and on light-atom quantum interfaces.

Viewpoint: A cooler way to operate atomic clocks

Dispersive probing of an atomic transition decreases the “dead time” of optical atomic clocks, potentially enabling more stable time reference standards. Read More »
