Abstract

Some expressions in our paper, particularly centered around its Eq. (14), were found to contain some errors. These errors were first noted and corrected in Ref. [1], including the expression in Eq. (1) below. In the following, we list the correct expressions, and identify the circumstances in which they would affect the results or conclusions. These corrections do not change either the results or the conclusions of the original paper. (Formula Presented). given in Eq. (6.36) of Ref. [2]. This derivation of hij starts from the Gaussian state formulation of the symmetric logarithmic derivative [3], and leads to Eq. (6.43) of Ref. [2], which matches Eq. (15) in our paper.
