Reply to ‘‘Comment on ‘Further investigations of the operationally defined quantum phase’ ’’

Abstract

It is pointed out in response to Hradil and Bajer [preceding Comment, Phys. Rev. A 48, 1717 (1993)] that C${\mathrm{^}}_{\mathit{M}}$ and S${\mathrm{^}}_{\mathit{M}}$ cannot both be measured together by scheme 1, whereas they can by scheme 2. There is no phase angle whose cosine and sine both vanish, and putting C+iS equal to zero for certain measurement outcomes breaks the connection with phase.
