摘要：
研究了量子态关于一组可用态的最佳凸逼近。通过等距变换，给出了一般的数学模型及其解，并给出了一个三重测不准等式关系。同时，我们给出了一个简洁的分解量子比特混合态的不等式判据。新的结果包括以前的作为特殊情况。我们的模型和方法可以应用于解决高维和多体场景中的类似问题
英文摘要：
We investigate the optimal convex approximation of the quantum state with respect to a set of available states. By isometric transformation, we have presented the general mathematical model and its solutions together with a triple uncertainty equality relation. Meanwhile, we show a concise inequality criterion for decomposing qubit mixed states. The new results include previous ones as special cases. Our model and method may be applied to solve similar problems in high-dimensional and multipartite scenarios
