Abstract
We study periodic grazing impact of some specific multi-vibro-impact oscillators which inherent Grover wave algorithm. Periodic energy transfer is caused from the internal resonance between the globally coupled impact and non-impact small oscillators. Impact small oscillator that can lose kinetic energy from the energy transfer to pragmatize grazing impact near the zero velocity. We derived the condition of perfect zero velocity graze impact by using wave algorithm. Trace of impact map in Bloch sphere shows figure of eight orbit, which corresponds to the switch of two different impact modes at the graze impact.
