Schrödinger-cat states: size classification based on evolution or dissipation
2004 (English)In: Proceedings of SPIE - The International Society for Optical Engineering: Vol. 5468 / [ed] Heszler P; Abbott D; GeaBanacloche JR; Hemmer PR, 2004, 335-343 p.Conference paper (Refereed)
The issue of estimating how "macroscopic" a superposition state is, can be addressed by analysing the rapidity of the state's evolution under a preferred observable, compared to that of the states forming the superposition. This fast evolution. which arises from the larger dispersion of the superposition state for the preferred operator, also represents a useful characteristic for interferometric applications. This approach can be compared to others in which a superposition's macroscopality is estimated in terms of the fragility to dissipation.
