The second page of the datasheet of Google's Weber system mentions a repetition rate. How is this repetition rate calculated?
I understand that repetition rate refers to how fast an experiment can be repeated (number of shots per second). I know that to reduce SPAM errors, one way of repeating an experiment is to wait for the T1 decay to ensure that the qubit is reset to |0> before starting the next shot. Other methods like restless measurements can also be used for increasing the repetition rate. My question, more precisely, is whether Sycamore relies on the T1 decay for repeating shots or uses some other technique.
Also, I don't understand how the number of shots affects the repetition rate. The Weber datasheet shows that the typical repetition rate for 2K repetitions is 0.3KHz while it's 2.1KHz for 20K repetitions.
