In the present paper we consider the problem of the description of an arbitrary generalized quantum measurement with outcomes in a measurable space. Analysing the unitary invariants of a separable statistical realization of a quantum instrument, we present the most general form of a possible integral representation of an instrument. We introduce the notion of a stochastic realization of an instrument and establish a one-to-one correspondence between the class of unitarily and phase equivalent… Expand

On the probabilistic description of a multipartite correlation scenario with arbitrary numbers of settings and outcomes per site
We consistently formalize the probabilistic description of multipartite joint measurements performed on systems of any nature. This allows us (1) to specify in probabilistic terms the differenceExpand

TLDR
It is shown that the dispersion of the wave packet does not increase to in½nity like for the free unobserved particle but tends to the …nite limit 1 = (~=2 m) where is the accuracy coe¢ cient of an indirect nondemolition measurement of the particle position, and ~ is Planck constant. Expand
