Query: Universal quantum gates based on both geometric and dynamic phases in
  quantum dots   A large-scalable quantum computer model, whose qubits are represented by the
subspace subtended by the ground state and the single exciton state on
semiconductor quantum dots, is proposed. A universal set of quantum gates in
this system may be achieved by a mixed approach, composed of dynamic evolution
and nonadibatic geometric phase.
