标题： Delocalized Excitation Transfer in Open Quantum Systems with Long-Range Interactions

摘要： 相干性与系统-环境相互作用之间的相互作用是广泛现象的基础，从量子信息处理到分子系统、生物分子和光化学材料中的电荷和能量转移。 在本工作中，我们使用一个具有长程相互作用的费伦克激子模型，耦合到阻尼的集体玻色子模式，以研究具有类似光收集复合物内部亚结构的给体-受体系统中的振动辅助传递过程。 我们发现某些离域的激子态可以最大化传递速率，并且在广泛的参数范围内，纠缠在耗散传递过程中得以保持。 我们研究了静态无序、白噪声和有限温度对传递的降低影响，并研究了传递效率如何随着二聚体单体的数量和每个单体的组分数量的变化而变化，找出哪些激子态导致最优传递。 最后，我们提供了一个现实的实验设置，以在模拟捕获离子量子模拟器中实现该模型。 由许多且日益复杂的单体组成的系统的模拟量子模拟可能为光收集材料的设计提供有价值的见解，特别是在本研究中检查的非微扰中间参数区域，其中经典模拟方法资源密集。 显示英文摘要

摘要： The interplay between coherence and system-environment interactions is at the basis of a wide range of phenomena, from quantum information processing to charge and energy transfer in molecular systems, biomolecules, and photochemical materials. In this work, we use a Frenkel exciton model with long-range interacting qubits coupled to a damped collective bosonic mode to investigate vibrationally assisted transfer processes in donor-acceptor systems featuring internal substructures analogous to light-harvesting complexes. We find that certain delocalized excitonic states maximize the transfer rate and that the entanglement is preserved during the dissipative transfer over a wide range of parameters. We investigate the reduction in transfer caused by static disorder, white noise, and finite temperature and study how transfer efficiency scales as a function of the number of dimerized monomers and the component number of each monomer, finding which excitonic states lead to optimal transfer. Finally, we provide a realistic experimental setting to realize this model in analog trapped-ion quantum simulators. Analog quantum simulation of systems comprising many and increasingly complex monomers could offer valuable insights into the design of light-harvesting materials, particularly in the non-perturbative intermediate parameter regime examined in this study, where classical simulation methods are resource-intensive.
