论文摘要
我们研究了三个耦合量子回忆录的纠缠和回忆特性。我们考虑基于通过电感器耦合的超导不对称鱿鱼体系结构的量子候选人。这三个量子回忆录以两个不同的几何形式排列：线性和三角形耦合构型。我们获得了多种相关措施，包括两分纠缠和三方负面性。我们发现，对于相同的量子回忆录，纠缠和纪念性遵循三角形的情况，在线性情况下是相同的行为。最后，我们研究了与三方负面性和纠缠一夫一妻制关系的多部分相关性，表明我们的系统具有真正的三方纠缠。我们的结果表明，多部分回忆系统中的量子相关性具有非平凡的作用，可用于设计用于量子神经网络和神经形态量子计算体系结构的量子回忆阵列。
We study the entanglement and memristive properties of three coupled quantum memristors. We consider quantum memristors based on superconducting asymmetric SQUID architectures which are coupled via inductors. The three quantum memristors are arranged in two different geometries: linear and triangular coupling configurations. We obtain a variety of correlation measures, including bipartite entanglement and tripartite negativity. We find that, for identical quantum memristors, entanglement and memristivity follow the same behavior for the triangular case and the opposite one in the linear case. Finally, we study the multipartite correlations with the tripartite negativity and entanglement monogamy relations, showing that our system has genuine tripartite entanglement. Our results show that quantum correlations in multipartite memristive systems have a non-trivial role and can be used to design quantum memristor arrays for quantum neural networks and neuromorphic quantum computing architectures.
