To further understand the evolution of the quantum state, we focus on one value of J and compare the measured Pauli set to that expected from single-qubit dephasing rates and J 12 (see supplemental information). Fig. 3a shows the Pauli set for the measured and expected quantum states for τ =40ns, wh ...
