Bounds and optimisation of orbital angular momentum bandwidths within parametric down-conversion systems
نویسندگان
چکیده
The measurement of high-dimensional entangled states of orbital angular momentum prepared by spontaneous parametric down-conversion can be considered in two separate stages: a generation stage and a detection stage. Given a certain number of generated modes, the number of measured modes is determined by the measurement apparatus. We derive a simple relationship between the generation and detection parameters and the number of measured entangled modes.

Orbital angular momentum spectrum of entangled two-photon states
We implement an interferometric method to measure the orbital angular momentum (OAM) spectrum of photon pairs generated by spontaneous parametric down-conversion. In contrast to previous experiments, which were all limited by the modal capacity of the detection system, our method operates on the entire down-conversion cone and reveals the complete distribution of the generated OAM. In this geom...
متن کاملDetermining the dimensionality of bipartite orbital-angular-momentum entanglement using multi-sector phase masks
The Shannon dimensionality of orbital-angular-momentum (OAM) entanglement produced in spontaneous parametric down-conversion can be probed by using multi-sector phase analysers [1]. We demonstrate a spatial light modulator-based implementation of these analysers, and use it to measure a Schmidt number of about 50. 4 Author to whom any correspondence should be addressed.

متن کاملQuantum correlations in optical angle-orbital angular momentum variables.
Entanglement of the properties of two separated particles constitutes a fundamental signature of quantum mechanics and is a key resource for quantum information science. We demonstrate strong Einstein, Podolsky, and Rosen correlations between the angular position and orbital angular momentum of two photons created by the nonlinear optical process of spontaneous parametric down-conversion. The d...
متن کاملSpatial mode filtering in spontaneous parametric down-conversion using aspheric lens
The aspheric convex lenses are used in the spontaneous parametric downconversion process to improve the detection efficiency of single-mode optical fibre. We found the position and focus of the lens have great effects upon the detection efficiency and spatial mode distribution of down-converted photons, which is in good accord with J. P. Torres’ theory [19]. Our results can be useful for improv...
متن کاملGeneration of hybrid polarization-orbital angular momentum entangled states.
Hybrid entangled states exhibit entanglement between different degrees of freedom of a particle pair and thus could be useful for asymmetric optical quantum network where the communication channels are characterized by different properties. We report the first experimental realization of hybrid polarization-orbital angular momentum (OAM) entangled states by adopting a spontaneous parametric dow...
