    "abstract": "We present the results of a numerical investigation which show the excitation\nof acoustoelectric modes of vibration in GaAs-based heterostructures due to\nsharp nano-second electric-field pulses applied across surface gates. In\nparticular, we show that the pulses applied in quantum information processing\napplications are capable of exciting acoustoelectric modes of vibration\nincluding surface acoustic modes which propagate for distances greater than\nconventional device dimensions. We show that the pulse-induced acoustoelectric\nvibrations are capable of inducing significant undesired perturbations to the\nevolution of quantum systems.",
