  Quantum noise with exchange and tunneling is studied within time-dependent
wave packets. A novel expression for the quantum noise of two identical
particles injected simultaneously from opposite sides of a tunneling barrier is
presented. Such quantum noise expression provides a physical (non-spurious)
explanation for the experimental detection of two electrons at the same side
under static potentials. Numerical simulations of the two-particle scattering
probabilities in a double barrier potential with an oscillatory well are
performed. The dependence of the quantum noise on the electron energy and
oscillatory frequency are analyzed. The peculiar behaviour of the dependence of
the quantum noise on such parameters is proposed as a test about the soundness
of this novel quantum noise expression, for either static or oscillatory
potentials.
