Measurements on current quantum processors are subject to hardware imperfections that lead readout errors. These errors manifest themselves as a bias in expectation values. Here, we propose very simple method forces the value appear multiplicative factor can be measured directly and removed at cost of an increase sampling complexity for observable. The assumes no specific form noise, but only r...

Many people confuse the standard deviation (SD) and the standard error of the mean (SE) and are unsure which, if either, to use in presenting data in graphical or tabular form. The SD is an index of the variability of the original data points and should be reported in all studies. The SE reflects the variability of the mean values, as if the study were repeated a large number of times. By itsel...

Methods The new method has been validated in digital phantoms with actual echo times and noise levels taken from 5 patients. To achieve numerical stability at low T2* values, a novel hybrid curve fitting method was developed. For low values the residuals were weighted with the signal intensity and for high values standard exponential fitting was used. The transition between high and low regions...
