This project is designed in SeQUeNCe (Simulator of QUantum Network Communication is an open-source tool that allows modeling of quantum networks including photonic network components, control protocols, and applications).
It is a model based on The Virtual Quantum Optics Laboratory Brian R. La Cour, Maria Maynard, Parth Shroff, Gabriel Ko, Evan Ellis Figure 30 (see Capture file) which represents an "Experimental setup for Bell state analysis showing confirmation of a |Ψ−> state". This set up is based on the effects of the Hong Ou Mandel Effect.
