Coherence time drifts on ibmq_bogota qubit 2: IBM’s publicly available coherence times on ibmq_bogota qubit 2 (vertical axis) are plotted against the date of calibration (horiztonal axis) up to one week before and after it was used in this study (08/10/20). Some of the reported coherence times violate \(T_2 \le 2 \cdot T_1\), thereby suggesting calibration errors.
