Abstract: 

We show that all composite quantum gates with vanishing dynamic phases are robust against control field strength errors. As examples of this observation, we show (1) how a robust composite rf-pulse in NMR is geometrically constructed and (2) a composite rf-pulse based on Trotter-Suzuki Formulas is a geometric quantum gate.
