广义三比特GHZ态的Cabello非定域性

Cabello's nonlocality for generalized three-qubit GHZ states

José L. Cereceda

摘要:

本文研究了广义GHZ态三量子比特系统的Cabello非定域性参数。对于这类状态,我们表明,CNA运行几乎所有的纠缠,并且CNA的最大成功概率是14%(约),这是最大纠缠GHZ态的结果。这个最大概率略高于标准的哈代非定域性参数(HNA)为三个量子比特,即12.5%。此外,我们还证明了在广义无信号理论的框架下,HNA和CNA在三量子比特系统中的成功概率最大可以达到50%。

英文摘要:

In this note, we study Cabello's nonlocality argument (CNA) for three-qubit systems configured in the generalized GHZ state. For this class of states, we show that CNA runs for almost all entangled ones, and that the maximum probability of success of CNA is 14% (approx.), which is attained for the maximally entangled GHZ state. This maximum probability is slightly higher than that achieved for the standard Hardy's nonlocality argument (HNA) for three qubits, namely 12.5%. Also, we show that the success probability of both HNA and CNA for three-qubit systems can reach a maximum of 50% in the framework of generalized no-signaling theory.
