Abstract
We show that the dimension of the density matrix in Fock representation is equal to the number of phases needed for accurate state reconstruction in optical homodyne tomography. We also derive a simple method for estimating the errors if the actual dimension is larger than the number of phases. © 1996 The American Physical Society.Keywords
