| Abstract: | Quantum computers may possess much greater computing power than classical computers.But it is one of key step for implementation of quantum computer to use geometric quantum phase to realize high-fidelity universal quantum gates,and its characteristic is to utilize global geometric features to avoid noise influence in some regions,then high-fidelity quantum gates are realized.In this paper,first we briefly introduce both fundamental and existing difficulties of quantum computer,finally discuss geometric quantum phase having relation with scheme such as nuclear magnetic resonance(NMS)、cavity-QED and superconducting Josephson-junction. |
