We calculate the linear-response conductance of a metallic single-electron pump using the path-integral Monte Carlo (PIMC) method. The Coulomb oscillations of the conductance are calculated to illustrate the influence of the Coulomb blockade effect on the system. Furthermore, the experimental conductance is compared with the calculated conductance of various gate voltage configurations and temperatures. The results are consistent even in the low-temperature regime, where significant quantum fluctuation occurs, and the semiclassical approximation fails. Consequently, the present investigation replicates the success of the PIMC approach while precisely describing the quantum fluctuation phenomena of single-electron devices.
