Triplet versus singlet entangled states in teaching the Einstein-Podolsky-Rosen paradox

The Einstein-Podolsky-Rosen paradox is considered using spin- singlet and triplet states prepared in the z-direction, after which measurements are made in a different direction, the x-direction, for example. An unexpected outcome and its usefulness for teaching is reported. The material will be of i...

Description
Summary:The Einstein-Podolsky-Rosen paradox is considered using spin- singlet and triplet states prepared in the z-direction, after which measurements are made in a different direction, the x-direction, for example. An unexpected outcome and its usefulness for teaching is reported. The material will be of interest to upper-year undergraduate quantum mechanics instructors and students.
