N比特W态的量子非局域性

Quantum Nonlocality of N-qubit W states

Chunfeng Wu, Jing-Ling Chen, L. C. Kwek, C. H. Oh

摘要:

提出了一种测试N个量子比特的量子非局域性的实验装置。该方法是Banaszek和Wodkiewicz [1]提出的光学装置的推广。N个量子比特的量子非定域性可以通过它对N个量子比特的贝尔不等式的破坏得到。实验中测得的关联函数用维格纳函数描述。还考虑了探测器效率不高的影响。

英文摘要:

An experimental setup for testing quantum nonlocality of N qubits is proposed. This method is a generalization of the optical setup proposed by Banaszek and Wodkiewicz [1]. The quantum nonlocality of N qubits can be obtained through its violation of N-qubit Bell inequalities. The correlation function measured in the experiment is described by the Wigner function. The effect of inefficient detector is also considered.
