论文摘要
IBM Q 53量子量子计算机的纠缠特性通过嘈杂的中间量子量子（NISQ）技术仔细检查。我们在IBM Rochester上研究具有多个量子位（n = 2至n = 7）的GHz样状态，并将其最大违规值与分析结果进行比较。 N Qubits正交测量的规则是为了进一步证明纠缠小于本地现实主义（LR）的最大值的合理性。测量的正交性是纠缠的另一个可靠标准，除了LR的最大值。我们的结果表明，当n <4 = 4时，IBM 53 Qubits的纠缠相当好，而对于较长的纠缠链，纠缠仅适用于某些特殊的连接。
Entanglement properties of IBM Q 53 qubit quantum computer are carefully examined with the noisy intermediate-scale quantum (NISQ) technology. We study GHZ-like states with multiple qubits (N=2 to N=7) on IBM Rochester and compare their maximal violation values of Mermin polynomials with analytic results. A rule of N-qubits orthogonal measurements is taken to further justify the entanglement less than maximal values of local realism (LR). The orthogonality of measurements is another reliable criterion for entanglement except the maximal values of LR. Our results indicate that the entanglement of IBM 53-qubits is reasonably good when N <= 4 while for the longer entangle chains the entanglement is only valid for some special connectivity.
