量子关联在基础物理学和量子信息领域中都有着重要的地位，近些年受到人们广泛的关注。量子dissonance是量子关联的一种，与纠缠一起构成系统的全部量子关联。在量子相变和噪声环境下研究量子dissonance的行为对阐明各种量子关联间的区别与联系有着重要意义。本项目计划研究量子dissonance和量子相变的关系及其在噪声环境下的动力学演化问题。主要包含三方面内容：（1）自旋链系统中量子dissonance和量子相变的关系；（2）噪声环境下两qubit系统量子dissonance的动力学演化；（3）经典场对量子dissonance抗噪声能力的影响。本研究为深入认识各种量子关联提供新的视角，为未来dissonance的研究和应用奠定重要的理论基础。

Quantum correlations have received great attention in recent years, since they occupy an important place in foundamential physics and quantum information theory. Quantum dissonance is one kind of quantum correlation, that is, the reminder of the whole quantum correlation excluding entanglement. The behavior of quantum dissonance in quantum phase transition and under noisy environment has great significance in illustrating the difference and connection between various quantum correlations. This project is planning to study quantum dissonance in quantum phase transition and its dynamical evolution under noisy environments. It mainly contains three parts: (1) The relation between quantum dissonance and quantum phase transition in one dimentional spin chain system; (2) Dynamical evolution of quantum dissonance of two-qubit system under noisy envionments; (3) Improving the anti-noise capability of dissonance by classical fields. This project provides a new perspective for in-depth understanding quantum correlations, and establishes theoretical foundation for future studies and applications of quantum dissonance.
