Suppose I create the very simple circuit
OPENQASM 2.0; include "qelib1.inc"; qreg q; x q; barrier q; x q;
and submit it to an IBM backend. How do I find the buffer time between the end of the first
X and the beginning of the second
X for a given backend? I've seen the number
~10 ns thrown around in the literature (see this paper above Fig. 1), but this value is not displayed in the calibration data for a device.
Just for clarify, I am NOT referring to the duration of
X but the duration of time between the
X pulses even "when it appears to be 0."
If there's a way to obtain it via Qiskit on a per-calibration basis, that's even better, but just a reference which verifies that
10 ns is a reasonable value would suffice.
