量子动力学半群与不可分解正映射

Quantum dynamical semigroups and non-decomposable positive maps

F. Benatti, R. Floreanini, M. Piani

摘要:

研究了有限维二分系统上正映射但非完全正映射的动力学半群,并分析了它们的生成元与不可分解性和束缚纠缠的关系。给出了一个导致4 × 4维有界纠缠密度矩阵的不可分解半群的例子。

英文摘要:

We study dynamical semigroups of positive, but not completely positive maps on finite-dimensional bipartite systems and analyze properties of their generators in relation to non-decomposability and bound-entanglement. An example of non-decomposable semigroup leading to a 4x4-dimensional bound-entangled density matrix is explicitly obtained.
