多体纠缠的最优动力学控制

Optimal dynamical control of many-body entanglement

Felix Platzer, Florian Mintert, Andreas Buchleitner

摘要:

制备高度纠缠的多体系统是基础科学和应用科学的核心挑战之一。粒子间相互作用和环境耦合的复杂性随着待纠缠子系统的数量迅速增加,使得对多体量子系统的控制要求更加严格。我们提出了一种方法,允许在一个纯粹的代数方式获得最优控制哈密顿。这些驱动一个复合量子系统迅速进入高度纠缠态,这种纠缠态对于给定的相互作用机制可以最有效地产生,并且具有对抗退相干的强大纠缠。

英文摘要:

The preparation of highly entangled many-body systems is one of the central challenges of both basic and applied science. The complexity of interparticle interaction and environment coupling increases rapidly with the number of to-be-entangled subsystems, rendering the requirements on the control of many-body quantum systems ever more restrictive. We propose an approach that allows to derive optimal control Hamiltonians in a purely algebraic fashion. These drive a composite quantum system rapidly into that highly entangled state which can be created most efficiently for a given interaction mechanism, and which bears entanglement that is robust against decoherence.
