意味（1）

(quantum mechanics, philosophy of physics) A conceptualised division separating the quantum system being observed from the classical system that comprises the observer's information, knowledge and conscious awareness.

The original Copenhagen way of describing the collapse process was tied to a mysterious thing called the Heisenberg cut. Everything lying below this cut was supposed to be described in the mathematical language of quantum mechanics, whereas everything lying above the cut was described either in the language of classical physics, or in psychological or mental terms. […] A principal move made by von Neumann was to show that the Heisenberg cut could be moved all the way up, so that reality was unambiguously separated into a purely mental part, and a part described in the mathematical language of quantum mechanics.
