    • With internal atomic degrees of freedom employed for the path marking, a recent atom-interferometry experiment investigated the equality of Eq. (1), with scaled results constant to within (Formula presented) but achieving unscaled values of only (Formula presented) [S. Dürr, T. Nonn, and G. Rempe, Phys. Rev. Lett. 81, 5705 (1998)].For the record we note that our work was simultaneous with and independent of Dürr, Nonn, and Rempe’s although their published account appeared earlier.

    • It is sometimes claimed that the quantization of matter is all one needs to explain detector clicks and that a semiclassical theory (quantized matter interacting with classical Maxwell fields) is capable of giving a full account. However, experiments (like those in 13) have proved that such a model incorrectly predicts physical results in some situations. Rather than adopting a semiclassical approach (which we know eventually fails) for some experiments and the quantum approach (which always works) for others, we feel compelled to use the latter picture throughout. Moreover, a semiclassical description is unavoidably inconsistent for theoretical reasons. Either the charged quantized matter would have to act as a source for the classical electromagnetic field or, if this is avoided by construction, action would not be properly paired with reaction.

    • For linear polarization states, the optimal knowledge-measurement axes lie exactly between the axes that would equalize the amplitudes from the two paths (and for which the visibility is maximum), i.e., if the light coming from paths 1 and 2 is polarized at (Formula presented) and (Formula presented) then the optimal knowledge basis is at (Formula presented)

    • In another series of measurements 21, the internal HWP was replaced by quartz rotators, relying only on optical activity whose net effect was to rotate the relative polarizations in the two paths by (Formula presented) When a linear polarization at (Formula presented) was input, there was basically never any interference without quantum erasure. Complete visibility could be restored using a linear analysis at (Formula presented) or a circular-polarization analysis. For a completely mixed state input, however, only the circular analysis (i.e., along the eigenmodes of the quartz) recovered complete visibility.
