Phys. Rev. A 70, 033408 (2004) [6 pages]Distilling angular momentum nonclassical states in trapped ionsReceived 14 May 2004; published 23 September 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 Schrödinger cat states. © 2004 The American Physical Society URL:
