  Constructing a set of universal quantum gates is a fundamental task for
quantum computation. The existence of noises, disturbances and fluctuations is
unavoidable during the process of implementing quantum gates for most practical
quantum systems. This paper employs a sampling-based learning method to find
robust control pulses for generating a set of universal quantum gates.
Numerical results show that the learned robust control fields are insensitive
to disturbances, uncertainties and fluctuations during the process of realizing
universal quantum gates.
