Generation of superpositions of classically distinguishable quantum states from optical back-action evasion
Shang Song, Carlton M. Caves, Bernard Yurke · Physical Review A · 1990
We describe a method for generating superpositions of classically distinguishable quantum states in an optical-frequency mode. The method uses the optical back-action-evading apparatus demonstrated recently by La Porta, Slusher, and Yurke [Phys. Rev. Lett. 62, 28 (1989)].
