Analyzing the three-polarizing-filter experiment as a quantum circuit
In the three-polarizing-filter experiment, two orthogonal polarizing filters block all light but then allow some amount when a third polarizing filter is placed oriented at a 45 degree angle between them.
Can we analyze this experiment through terms…

Understanding polarizing beam splitters
I have been trying to understand this heralded CNOT gate on photons but I have some questions regarding polarizing beam splitters:
The way I understand it, a PBS lets the photon through if the photon is polarized a certain direction, but as I…
