In this project, we study theoretically how the current fluctuations and their statistics can be measured in mesoscopic systems. We study the limitations of classical measurement schemes in measuring the third and higher cumulants of fluctuations, and consider novel mesoscopic detectors, which allow for a sensitive and large-bandwidth detection of noise. Moreover, in such detectors, one can access the nonsymmetrized noise, which is not possible in classical schemes. We also examine a scheme for the calculation of different moments of current statistics, exploiting the quasiclassical Keldysh counting-field method.
