The variable wave plates could be […]
Why does a BBO crystal create entangled photons? If we pump a beta barium borate (BBO) crystal, we get one circle of vertically polarized photons | V ⟩ |V⟩ and an intersecting circle of horizontally polarized ones | H ⟩ |H⟩: http://quantum.ustc.edu.cn/old/img/image002.gif At the intersection points of the circles, we get entanglement | ψ ⟩ […]
