Distilling angular momentum nonclassical states in trapped ions
Benedetto Militello, ANTONINO MESSINA
Abstract
In the spirit of quantum nondemolition measurements, we show that by exploiting suitable vibronic couplings and repeatedly measuring the atomic population of a confined ion, it is possible to distill center-of-mass vibrational states with a well-defined square of angular momentum or, alternatively, angular momentum projection Schr\"odinger cat states.
