High-dimensional maximally entangled photon pairs in parametric
down-conversion
Photon pairs generated from spontaneous parametric down-conversion are a well-established method to realize entangled bipartite photonic systems. Laguerre-Gaussian modes, which carry orbital angular momentum (OAM), are commonly exploited to engineer high-dimensional entangled quantum states experimentally. For Hilbert spaces with dimension d>2, maximally entangled states (MES) help to improve the capacity …
