Simulations of RC show better performance as the rate of coherent errors is reduced
Simulations of randomized compiling (RC) show that RC performs better as the error rate of coherent errors is reduced. This is demonstrated in the plot above for…

How many randomly compiled circuits do we need to see a benefit from RC?
A valid question to ask is, how many randomly compiled circuits do we need to see a benefit from randomized compiling (RC)? We re-analyzed the random circuit sampling data presented on the RC project page to answer this question. For each circuit depth (K) in which we generated random circuits, we computed the convergence of

State tomography on a single-qubit
We performed state tomography on a single-qubit at three different points during a random sequence of gates (after 10 gates, after 100 gates, and after 200 gates). This clearly demonstrates the intuition behind randomized compiling (RC): coherent errors can build up as a function of circuit depth, resulting in errors in the bare quantum state
