We discuss qubit-state superpositions in the probability representation of quantum mechanics. We study probability distributions describing separable qubit states. We consider entangled states on the example of a system of two qubits (Bell states) using the corresponding superpositions of the wave functions associated with these states. We establish the connection with the properties and structure of entangled probability distributions.
我们在量子力学的概率表示中讨论量子比特态叠加。我们研究描述可分离量子比特态的概率分布。我们以两个量子比特的系统（贝尔态）为例，利用与这些态相关的波函数的相应叠加来考虑纠缠态。我们建立了与纠缠概率分布的性质和结构的联系。
