TL;DR: In this paper, a way to construct an extension of the classical compound state in quantum systems has been presented, which is called the quantum compound state (QCS) and is defined as follows:
Abstract: When a state of a physical system dynamically changes to another state, it is important to know the correlation existing between the initial state and the final state. This correlation is described by a compound state (measure) in classical systems. In this note, we show a way how to construct such a compound state in quantum systems which is an extension of the classical compound state.

TL;DR: In this paper, the quantum-mechanical properties of spin-state superposition for fermions have been demonstrated using coherent superposition of two neutron waves with mutually opposite polarisation direction.
