Increasing the dimension in high-dimensional two-photon orbital angular momentum entanglement
Increasing the dimension in high-dimensional two-photon orbital angular momentum entanglement
Any practical experiment utilising the innate D-dimensional entanglement of the orbital angular momentum (OAM) state space of photons is subject to the modal capacity of the detection system. We show that given such a constraint, the number of measured, entangled OAM modes in photon pairs generated by spontaneous parametric down-conversion …
