利用广义贝尔不等式检测N粒子纠缠

Detection of N-particle entanglement with generalized Bell inequalities

Wieslaw Laskowski, Marek Zukowski

摘要:

我们表明,广义贝尔型不等式,明确涉及旋转对称性的物理定律,是非常有效的区分真正的N粒子量子关联和相关涉及较少的粒子。这适用于各种类型的广义部分可分性。我们还严格证明了新的贝尔不等式被GHZ态最大程度地破坏,并找到了N量子比特关联函数的一个非常简便的描述.

英文摘要:

We show that the generalized Bell-type inequality, explicitly involving rotational symmetry of physical laws, is very efficient in distinguishing between true N-particle quantum correlations and correlations involving less particles. This applies to various types of generalized partial separabilities. We also give a rigorous proof that the new Bell inequalities are maximally violated by the GHZ states, and find a very handy description of the N-qubit correlation function.
