摘要：

We propose a which path quantum eraser scheme based on a recent experiment by Eichmann er nl. [Phys. Rev. Lett. 70, 2359 (1993)] involving two four-level atoms. We show that the quantum eraser can be used for the detection of the decoherence time of macroscopic or mesoscopic entangled superpositions of pointer states of a meter with one of the two atoms, by the visibility of the interference pattern. [S1050-2947(99)51410-8].
