摘　　要：量子相干性作为一种重要的物理资源,是量子力学最基本的特性之一,同时也是量子信息的优势所在,吸引了大量科学研究者的兴趣和注意力。主要探讨常见量子相干度量下高维量子系统中最大相干混合态的相干值。通过计算给出了高维量子系统中最大相干混合态在6种常见相干度量下的相干值的解析表达式。Quantum coherence,as an important physical resource,is one of the most basic characteristics of quantum mechanics,and it is also the advantage of quantum information,which attracts the interest and attention of a large number of scientific researchers.This paper mainly discusses the coherent values of the maximally coherent mixed states in high-dimensional quantum systems under common quantum coherence measures.The analytical expressions of the coherent value of the maximally coherent mixed state in a high-dimensional quantum system are calculated under six common coherent measures.
