“…The (unnormalized) state of the LO field after M detections is given in Eq. (10). By tracing out the remaining packets as Tr (|αe iϕ αe iϕ |) ⊗(N −M ) = 1, the joint probability distribution of the outcomes is calculated as…”

Optical homodyne detection is examined in view of the joint probability distribution. The usual view is that the relative phase between independent laser fields is localized by photon-number measurements in interference experiments such as homodyne detection. This is why operationally coherent states for laser fields are used in the description of homodyne detection and optical quantum-state tomography. Here, we elucidate these situations by considering the joint probability distribution and the invariance of homodyne detection under the phase transformation of optical fields.

“…This provides a typical example for the apparent relevance of the coherent state as the laser field. Then, there have been a lot of debates concerning the quantum state of laser and optical coherence (see [5][6][7][8][9][10][11][12][13], and references therein). The essential problem is whether the use of the coherent state of Eq.…”
