Distilling angular momentum nonclassical states in trapped ions
arXiv:quant-ph/0405079 · doi:10.1103/PhysRevA.70.033408
Abstract
In the spirit of Quantum Non-Demolition Measurements, we show that 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 well defined square of angular momentum or, alternatively, angular momentum projection Schrödinger cat states.
