Distilling angular momentum nonclassical states in trapped ions
Benedetto Militello, ANTONINO MESSINA · Physical Review A · 2004
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.
