AI 中文摘要
纠缠是量子技术的关键资源。我们证明，采用量子姆潘巴效应的协议可实现纠缠产生的指数级加速，或减缓其衰减。本文引入两种具有不同操作意义的纠缠姆潘巴效应，分别聚焦于快速达到纠缠的某一阈值或实现渐近稳态值。研究表明，纠缠姆潘巴效应依赖于所选的纠缠度量；结合团簇消除方法，多体量子系统也能从纠缠产生的指数级加速中受益，本文以耗散长程伊辛链为例对此进行了验证。
英文摘要
Entanglement is a key resource for quantum technologies. We show that protocols employing quantum Mpemba effects allow one to exponentially accelerate the generation of entanglement, or to slow down the decay thereof. Two entanglement Mpemba effects with different operational meaning are introduced, focusing either on the task of rapidly generating a certain threshold value for entanglement or on achieving the asymptotic steady-state value. We show that entanglement Mpemba effects depend on the chosen entanglement measure. Using cluster elimination methods, many-body quantum systems also benefit from the exponential speedup of entanglement generation, as we demonstrate for a dissipative long-range Ising chain.
