| 中文摘要 | we study the entanglement degree of electron pairs emitted from an s-wave superconductor, which couples to two normal leads via a single-level quantum dot. within the framework of scattering matrix theory. the concurrence is used to quantify the entanglement. and the result shows that the entanglement degree is generally influenced by the initial separation of the two electrons in a cooper pair and the normal transmission eigenvalues t-1, t-2. but it is only determined by the eigenvalues in the tunnelling limit, t-1. t-2 << 1, what is more. it is measurable.
