Ah: "In each round n = 0, 1, 2, … of the experiment, agent F¯¯¯¯ tosses a coin and, depending on the outcome r, polarises a spin particle S in a particular direction. Agent F then measures the vertical polarisation z of S" https://www.nature.com/articles/s41467-018-05739-8 https://www.nature.com/articles/s41467-018-05739-8
