Abstract
We show that the physically absurd state obtained by Vorontsov and Rembovsk y [Phys. Lett. A 254 (1999) 7] results from an unphysical choice of approxi mate phase measurement and not from the phase formalism itself as claimed. Thus their assertion that it is impossible to perform even an approximate m easurement of phase is unfounded. (C) 1999 Published by Elsevier Science B. V. All rights reserved.
