Macroscopic superpositions via nested interferometry: finite temperature and decoherence considerations
arXiv:1207.1946 · doi:10.1088/1367-2630/14/11/115025
Abstract
Recently there has been much interest in optomechanical devices for the production of macroscopic quantum states. Here we focus on a proposed scheme for achieving macroscopic superpositions via nested interferometry. We consider the effects of finite temperature on the superposition produced. We also investigate in detail the scheme's feasibility for probing various novel decoherence mechanisms.
