论文摘要
我们回顾了一些2量状态的参数家族，这些族的同意和最大单线分数（MSF）具有不同的行为，甚至相反的行为。对于这项工作中考虑的各州，最大可实现的保真度（MAF）是由Verstraete和Verschelde在2003年得出的数量，显示出更好的一致性与并发，并且符合所需的重要特征，即被认为是良好的纠缠措施。
We review some parametric families of 2-qubit states for which concurrence and maximal singlet fraction (MSF) have different and even opposite behaviour. For states considered in this work, maximal achievable fidelity (MAF), a quantity derived by Verstraete and Verschelde in 2003, shows a better agreement with concurrence and complies with important features required to be considered a good entanglement measure.
