Abstract

We propose a new setup to demonstrate quantum eraser, using spin-1/2 particles in a modified Stern-Gerlach setup, with a double slit. The "which-way" information can be erased simply by applying a transverse magnetic field with an additional magnet, resulting in the emergence of two complementary staggered interference patterns. Use of the classic Stern-Gerlach setup, and the unweaving of the washed out interference without any coincident counting, is what makes this proposal novel.
