Universal Quantum Gates Based on Both Geometric and Dynamic Phases in Quantum Dots
Kaiyu Yang, Shi-Liang Zhu, Wang Zi-Dan · Chinese Physics Letters · 2003
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 nonadiabatic geometric phase.
