局域操作引起的纠缠放大

Entanglement magnification induced by local manipulations

Raffaele Romano

摘要:

研究了当局域动力学参数在时间演化过程中不能改变时,在幺正动力学下演化的量子比特对的纠缠能力。与快速本地控制制度,我们发现,本地和非本地的动态贡献是严格相互关联的。此外,通过适当地初始化两方的特征能量,可以大大增加纠缠能力。

英文摘要:

We study the entanglement capability of the evolution of a pair of qubits evolving under unitary dynamics, when the local dynamical parameters cannot be modified during the time-evolution. Unlike the fast local control regime, we find that local and non-local contributions to the dynamics are strictly interconnected. Moreover, it is possible to strongly increase the entanglement capability by suitably initializing the characteristic energies of the two parties.
