Fast Super Robust Nonadiabatic Geometric Quantum Computation

Abstract

Nonadiabatic geometric quantum computation (NGQC) provides a means to perform fast and robust quantum gates. To enhance the robustness of NGQC against control errors, numerous solutions have been proposed by predecessors. However, these solutions typically result in extended operation times for quantum gates. In order to maintain the robustness of quantum gates to control errors while shortening operation times to minimize the effects of decoherence, we introduce Fast Super Robust NGQC(FSR-NGQC). This approach achieves faster speeds when operating small-angle rotation gates. Through numerical calculations, we have demonstrated the performance of our scheme in a decoherence environment. The results show that our scheme achieves higher fidelity, thus enabling fast and robust geometric quantum computing.
