By taking advantage of the high‐dimensional Hilbert space for orbital angular momentum and using Perfect Vortex beams as their carriers, researchers in South Africa have presented a proof‐of‐principle implementation of a high‐dimensional quantum secret sharing scheme. This scheme is experimentally implemented with a fidelity of 93.4%, for 10 participants in =11 dimensions. The implementation can easily be scaled to higher dimensions and any number of participants, opening the way for securely distributing information across a network of nodes…read more.
