We study electron spectra and electron tunneling in double quantum systems: quantum wells (QWs), quantum dots (QDs) and quantum rings (QRs). We especially study the relation between their chaotic properties and tunneling. In particular we compare the tunneling in DQW with chaotic and regular geometry. We consider the correlation between electron localization and quasi-doublet splitting for complete spectrum in two and three dimensions DQD. We show the effect of increasing of the tunneling rate in chaotic quantum system. A small violation of the symmetry drastically affects tunneling.
