Fig. 5: Generation of genuine qudit entanglement.

The measured state fidelity for d = 2, 3, 4, 5 is shown as blue data points and the corresponding concurrence as orange squares. The ideal values for maximally entangled states (the experimental target states) are shown as dashed (dotted) lines. The gray shaded bars represent the lower bound on the fidelity (blue data points) for certifying maximal Schmidt number entanglement, while the gray horizontal lines indicate the concurrence Cd for a maximally entangled state in dimension d. Error bars correspond to one standard deviation of experimental shot noise.
