    • Our treatment of the finite transport voltage is equivalent to the widely used one (Refs. 58, 59, 60, 61, 62, 63,), where the voltage difference between two leads is included in the initial distribution function. Two treatments are related each other by a gauge transformation

    • There are two differences between our definition and that in Ref. 30., First, we use the generating functional for connected Green function W rather than Z, because we are interested in the correlation function of the current (or charge) fluctuation operator. Second, we propose the modified expression for the noise: Besides the standard definition, the first term of Eq. (29) or Eq. (30), we introduce the additional second term. It circumvents the uncertainty related to the order of operators (Appendix A)

    • We can confirm that the term (Formula presented) is 0 from the analytic properties of the step function (Formula presented) viz., (Formula presented) The standard definition for noise, the first term of Eq. (29) or Eq. (30), includes such terms, and thus one must remove them carefully. Our definition does not include such terms, which simplifies practical calculations for the second moment
