摘要:

我们研究了三个耦合量子忆阻器的纠缠和忆阻特性。我们考虑基于超导非对称SQUID架构的量子忆阻器,其通过电感器耦合。这三个量子忆阻器以两种不同的几何形状排列:线性和三角形耦合配置。我们得到了各种相关的措施,包括二体纠缠和三重负性。我们发现,对于相同的量子忆阻器,纠缠和忆阻性遵循相同的行为,三角形的情况下和相反的情况下的线性。最后,我们研究了具有三重负性和纠缠一夫一妻关系的多体关联,证明了我们的系统具有真正的三重纠缠。我们的研究结果表明,量子关联在多体忆阻系统中具有重要的作用,可以用来设计量子忆阻器阵列的量子神经网络和神经形态量子计算架构。

英文摘要:

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.
