  It is demonstrated that 'quantum eraser' (QE) experiments do not erase any
information. Nor do they demonstrate retrocausation or 'temporal nonlocality'
in their 'delayed choice' form, beyond standard EPR correlations. It is shown
that the erroneous erasure claims arise from assuming that the improper mixed
state of the signal photon physically prefers either the 'which way' or 'both
ways' basis, when no such preference is warranted. The latter point is
illustrated through comparison of the QE spatial state space with the spin-1/2
space of particles in the EPR-spin experiment.
