Idea

Given a measurable space XX and a Hilbert space HH, then a positive-operator–valued measure (POVM) is essentially a probability measure on XX with values in the positive operators on HH.

Any such induces a quantum operation and these are precisely the quantum operations which encode quantum measurement.
