Quantum secret sharing is the art of securely sharing information between more than two people in such a way that its reconstruction requires the collaboration of a certain number of parties. Here, by taking advantage of the high‐dimensional Hilbert space for orbital angular momentum and using Perfect Vortex beams as their carriers, a proof‐of‐principle implementation of a high‐dimensional quantum secret sharing scheme is presented. This scheme is experimentally implemented with a fidelity of 93.4%, for 10 participants in d = 11 dimensions—the highest number of participants and dimensions to date. 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.
