  Since the pioneering works by Landau, Zener, St\"uckelberg, and Majorana
(LZSM), it has been known that driving a quantum two-level system results in
tunneling between its states. Even though the interference between these
transitions is known to be important, it is only recently that it became both
accessible, controllable, and useful for engineering quantum systems. Here, we
study systematically various aspects of LZSM physics and review the relevant
literature, significantly expanding the review article in [Shevchenko, S. N.,
S. Ashhab, and F. Nori (2010), "Landau-Zener-St\"uckelberg interferometry,"
Phys. Rep. 492, 1].
