The classically forbidden tunneling process has intrigued scientists for decades. Recently, the invention of high-precision attoclock techniques in strong laser ionization as well as so-called reaction microscopes for high-resolution momentum measurements have allowed to raise the fundamental question on how classical dynamics emerges in quantum tunneling. Combining experimental and theoretical investigations, we confirm that the leading quantum mechanical Wigner treatment of tunneling in strong field ionization reveals a nonzero tunneling delay time as well as a nonvanishing longitudinal momentum [1].
