Abstract

Recent studies have found a positive operator measure associated with quantum homodyne tomography which, with the state of a system, leads to the probability distribution phtT. Here, we introduce the general integral kernel for the state T, which arises from considering the General Wigner function, and show that phtT can still be expressed by the matrix elements of T when the general integral kernel is used, giving the same results as the standard integral kernel.
