What does randomized compiling try to change?

Question: What is the goal of randomized compiling when coherent errors are present? A) To estimate the full process matrix of every gate before execution B) To replace logical computation with classical randomized simulation C) To tailor coherent errors into a more stochastic effective noise model while preserving the intended computation on average D) To remove the need for measurement-error mitigation Correct: C Explanation: Randomized compiling inserts random gates and compensating corrections so that the ideal computation is unchanged. Averaged over randomizations, coherent error buildup can be converted into a more stochastic form that is easier to model and less adversarial.
