Manipulation and Certification of High-Dimensional Entanglement through a Scattering Medium

High-dimensional entangled quantum states improve the performance of quantum technologies com-pared to qubit-based approaches. In particular, they enable quantum communications with higher infor-mation capacities or enhanced imaging protocols. However, the presence of optical disorder such as atmospheric turbulence or biological tissue perturbs quantum state propagation and hinders their practical use. Here, we demonstrate a wavefront shaping approach to transmit high-dimensional spatially entangled photon pairs through scattering media. Using a transmission matrix approach, we perform wave-front correction in the classical domain using an intense classical beam as a beacon to compensate for the disturbances suffered by a copropagating beam of entangled photons. Through violation of an Einstein-Podolski-Rosen criterion by 988 sigma, we show the presence of entanglement after the medium. Furthermore, we certify an entanglement dimensionality of 17. This work paves the way toward manipulation and transport of entanglement through scattering media, with potential applications in quantum microscopy and quantum key distribution.
