  "abstract": "We report the first measurement of the \\emph{dynamical response} of shot noise (measured at frequency $\\omega$) of a tunnel junction to an ac excitation at frequency $\\omega_0$. The experiment is performed in the quantum regime, $\\hbar\\omega\\sim\\hbar\\omega_0\\gg k_BT$ at very low temperature T=35mK and high frequency $\\omega_0/2\\pi=6.2$ GHz. We observe that the noise responds in phase with the excitation, but not adiabatically. The results are in very good agreement with a prediction based on a new current-current correlator.",
