Abstract

A pump photon in a nonlinear optical crystal may split into two highly correlated daughter photons, satisfying energy and momentum conservation, in turn leading to energy-time and momentum entanglement, respectively. A novel arrangement employing two adjacent, relatively thin, nonlinear crystals, which are operated with type-I phase matching is presented. The energy and momentum entanglements of the photon pairs remain, so that the complete state is actually multiply- or hypertangled. Moreover, simply by varying the pump polarization, it can create states that are nonmaximally entangled.
