Comment on "The Quantum State of a Propagating Laser Field"
arXiv:quant-ph/0112020
Abstract
We comment on the theoretical quantum state of a propagating laser field proposed by van Enk and Fuchs [quant-ph/0104036, quant-ph/0111157] and clarify that the multimode description of the propagating laser field does not modify our analysis of continuous variable quantum teleportation [quant-ph/0103147]. Furthermore we point out that the ``complete measurements'' discussed by van Enk and Fuchs have not been achieved by existing technology and may not be possible even in principle.
