The two-dimensional diffusive metal stabilized at the interface of SrTiO3 and the Mott insulator LaTiO3 has challenged many notions related to the formation and electronic behavior of the two-dimensional electron gas at the well studies LaAlO3-SrTiO3 interface. Here we discuss specifically the stability of the superconducting phase at LaTiO3 - SrTiO3 interface and the nature of the superconductor - normal metal quantum phase transition driven by a magnetic field and by carrier density modulation through electrostatic gating. The nature of the superconducting condensate is highlighted in the light of the Ti - t2g orbital driven bands and their filling in the presence of a strong Rashba spin - orbit interaction.
