It is shown that in many-electron systems quantum transfer amplitudes and\nthus transfer probabilities may be strongly influenced by fast fluctuating\nfields, in particular, caused by simultaneous electron transfers. Corresponding\nmutual interplay of many electron jumps, arising at the fundamental level of\nquantum phases, results in long-correlated (1/f type) conductance fluctuations.\nHowever, thats could not be theoretically catched if neglect the real\ndiscreteness of quantum energy spectra and use the continuous spectrum\napproximation when building kinetic theory. Basing on first principles, the\nestimates of low-frequency fluctuations of tunneling conductance are presented.\n
