Coherence Measurements: (a) Values of the Stokes parameters of the reduced state of the coin: observed (solid red lines), ideal model (dashed lines) and realistic model (blue, solid lines). (b) Hilbert–Schmidt distance between and , the maximally mixed, asymptotic state: observed data (red), ideal model (turquoise) and realistic model (blue). The insets show the experimental density matrix for the three chosen steps. Statistical errors are smaller than the symbol size. The depicted error bars are calculated using a numerical simulation of all relevant systematic errors and are discussed in detail in the Methods section.
