Bayesian homodyne and heterodyne tomography: erratum

Open Access Open Access

Abstract

We correct typographical errors in Eq. (15) in [Opt. Express 30, 15184 (2022) [CrossRef]  ]. These errors were not present in the actual formulas used to calculate the results of the paper, so all results remain unaffected.

Erratum

The corrected version [1] of Eq. (15) for squeezed vacuum is

$$|{\psi_g}\rangle = \frac{1}{\sqrt{\cosh r}} \sum_n \frac{\sqrt{(2n)!}}{n!} \left(\frac{1}{2}\tanh r \right)^n |{2n}\rangle.$$
