Scientists just found a hidden 48-dimensional world in quantum light

Scientists at the University of the Witwatersrand in South Africa, working with collaborators from Huzhou University, have uncovered a surprising feature in one of the most widely used tools in quantum optics. They found that standard methods for producing entangled photons can contain previously unseen topological structures. In their experiments, these structures reached a record 48 dimensions and included more than 17,000 distinct topological signatures, creating a vast new "alp...
