Suppose you have two polarization-entangled photons A and B in the following state: \begin{equation} \Phi=\frac{1}{\sqrt{2}}\bigl(\left|H_{A},H_{B}\right\rangle + \left| V_{A},V_{B}\right\rangle … =\left|-45_{A},-45_{B}\right\rangle \end{equation} or just the polarization of the photon A? \begin{equation} \Phi=\frac{1}{\sqrt{2}}\bigl(\left|-45_{A},H_{B}\right\rangle + \left| -45_{A},V_{B}\right …

I'm wondering if anyone can help me understand how a polarizer changes the quantum state of two polarization-entangled photons. I haven't found a clear description in the literature. Suppose you … have two polarization-entangled photons A and B in the following state: \begin{equation} \Phi=\frac{1}{\sqrt{2}}\bigl(\left|H_{A},H_{B}\right\rangle + \left| V_{A},V_{B}\right\rangle\bigr) \end{equation …

When does passing through a polarizer change phase besides just changing polarization? Consider three cases: A polarizing beam splitter (PBS) is a clear case. Horizontally polarized light leaves …

I'm trying to understand how polarizers affect bunched photons. Or, more generally, how a projection operator affects a two-photon state corresponding to photon bunching. Toy example: Imagine you hav …
