Abstract:	We report on the non-adiabatic interaction between 2D acoustic phonons and an artificial 2-level system in a GaAs/AlGaAs heterostructure. The 2-level system is formed by two discrete energy levels inside a double quantum dot, and monochromatic surface acoustic waves (~2 GHz) are generated by an on-chip interdigital transducer (IDT). An IDT for better performance is proposed.
