Modern light generation technology offers extraordinary capabilities for sculpting light pulses, with full control over individual electric field oscillations within each laser cycle. These capabilities are at the core of lightwave electronics -- the dream of ultrafast lightwave control over electron dynamics in solids, on a few-cycle to sub-cycle timescale, aiming at information processing at tera-Hertz to peta-Hertz rates. At the same time, quantum materials have opened the way to dissipationless electron transport and to the possibility to harness extra electronic degrees of freedom, such as the valley pseudospin, that can be used as additional information carriers. In this talk, I will show a robust and general approach to control and probe the topological properties of 2D quantum materials by controlling the sub-cycle structure of non-resonant driving fields at a few-femtosecond timescale. I will show that this control permits non-resonant excitation, manipulation and reading of valley-polarized electrons in 2D materials on timescales orders of magnitude shorter than valley lifetime, crucial for practical implementation of valleytronic devices.
