Physical Review A
Reply to ‘‘Comment on ‘Phase-difference operator’ ’’
Alfredo Luis, Luis Lorenzo Sánchez-Soto
Abstract
In response to the objection raised by Pegg and Vaccaro [the preceding Comment] we point out that their example is not a difficulty in directly representing the phase difference by the ${\mathrm{\ensuremath{\Phi}}}_{12}$ operator. In fact, we argue that it is a property common to a wide range of phase descriptions, including the Pegg-Barnett formalism.
