We study entanglement distillability of bipartite mixed spin states under Wigner rotations induced by Lorentz transformations. We define weak and strong criteria for relativistic isoentangled and isodistillable states to characterize relative and invariant behavior of entanglement and distillability. We exemplify these criteria in the context of Werner states, where fully analytical methods can be achieved and all relevant cases presented.
我们研究了洛伦兹变换诱导的维格纳旋转下二分混合自旋态的纠缠可提纯性。我们定义了相对论等纠缠态和等可提纯态的弱标准和强标准,以表征纠缠和可提纯性的相对行为和不变行为。我们在韦尔纳态的背景下举例说明了这些标准,在这种情况下可以实现完全解析的方法并呈现所有相关情况。
