I want to know the fidelity (or error rate) of the preparation ($|0\rangle$) How can I have it?

  • $\begingroup$ Fidelity is a measure of the "closeness" of two quantum states. You need another state to compared your $|0 \rangle$ to. $\endgroup$ – Victory Omole Feb 27 at 1:43
  • $\begingroup$ @VictoryOmole Thank you for the answer, but I mean the fidelity of the preparation operation (|0>) of IBMQ. As you know, in the IBM Q website, the error rates of all the operations are posted except the preparation. Therefore, I posted this question. I want to know how much the initialized state is closed to |0>. $\endgroup$ – Yongsoo Feb 27 at 4:42
