We develop an analytical approach using form factors to compute time dependent correlations in integrable quantum impurity problems. As an example, we obtain for the first time the frequency dependent conductivity {ital G}({omega}) for the tunneling between edges in the {nu}=1/3 fractional quantum Hall effect and the spectrum {ital S}({omega}) of the spin-spin correlation in the anisotropic Kondo model and equivalently in the double well system of dissipative quantum mechanics, both at vanishing temperature. {copyright} {ital 1996 The American Physical Society.}
