a The von Neumann entanglement entropy and b the degree-2 Rényi entanglement entropy of the five-qubit experiment on the H1-1 quantum computer. c The von Neumann entanglement entropy and d the degree-2 Rényi entanglement entropy of the seven-qubit experiment. Error bars represent one standard deviation due to sampling error.
