Suppose I create the very simple circuit
OPENQASM 2.0;
include "qelib1.inc";
qreg q[1];
x q[0];
barrier q[0];
x q[0];
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.
