相互作用电子占据的空间畴的量子纠缠
Quantum entanglement of space domains occupied by interacting electrons
摘要：
用自旋-自旋关联函数表示占据两个空间区域-畴-的两个电子的自旋纠缠。从两个电子的散射产生的纠缠到一对量子比特的纠缠，由一个双量子点耦合到导线上的几个例子证明了形式主义的力量。在后一种情况下，分析了由于近藤效应导致的纠缠崩溃。
英文摘要：
Spin-entanglement of two electrons occupying two spatial regions -- domains -- is expressed in a compact form in terms of spin-spin correlation functions. The power of the formalism is demonstrated on several examples ranging from generation of entanglement by scattering of two electrons to the entanglement of a pair of qubits represented by a double quantum dot coupled to leads. In the latter case the collapse of entanglement due to the Kondo effect is analyzed.
