Analyzes complex detector network scenarios.

Suggests evidence for the Heisenberg cut.

Abstract

A range of quantum optics experiments is discussed in which the apparatus can be modified by detector outcomes during the course of any run. Starting with a single beamsplitter network, we work our way through a series of more complex scenarios, culminating with a proposed self-intervening experiment which could provide evidence for the existence of the Heisenberg cut, the supposed boundary between classical and quantum physics.
