摘要: We characterize the entanglement in position and momentum of photon pairs generated type-II parametric down-conversion. Coincidence maps positions near-field far-field planes are observed two transverse dimensions using scanning fiber probes. estimate covariance matrix an effective two-mode system apply criteria for based on matrices to certify space–momentum entanglement. The role higher-order spatial modes observing between photons is discussed.
