Entangled states in interferometry
2002 (English)In: Acta Physica Polonica. A, ISSN 0587-4246, Vol. 101, no 1, 37-46 p.Article in journal (Refereed) Published
We show how some entangled quantum states can be used to improve interferometric measurements. We describe why Schrodinger-cat states are very sensitive to relative-phase shifts and why relative-phase states as described by A. Luis and L.L. Sanchez-Soto resolve the interval [0, 2pi] well. We also describe how the quantum concept of well-defined relative-phase and the classical visibility of an interference pattern are related.
