High-dimensional entanglement generation based on a Pancharatnam-Berry phase metasurface
文献摘要：
High-dimensional entanglement is of great importance in quantum communications and can be realized by en-coding information on multiple degrees of freedom(DoFs)of the photons.Conventionally,the realization of such high-dimensional entanglement involves different combinations of bulky optical elements.In this work,we present the use of a single dielectric metasurface to generate high-dimensional entanglement by modulating multi-DoFs of photons.By sending one of the polarization-entangled photons to interact with the metasurface,we encode path,spin angular momentum,and orbital angular momentum information to the original state.We achieve a four-qubit quantum state in the experiment.To verify it,we experimentally demonstrate the nonlocal correlations between the two photons by recording the correlated images,and we also perform a quantum state tomography measurement.This scheme can be applied to on-chip quantum state manipulation,which is prom-ising in quantum communication with integrated components.
