标题： Engineering Quantum-Enhanced Transport by Supertransfer

摘要： 量子系统组分的集体行为能够显著改变系统内部动力学过程的速率。一个典型的集体效应是超辐射，即一群发射器相比独立发射器，其辐射发射率得到了增强。然而，能量传输中的集体效应研究较少，尤其是超级转移——由于离域激发导致供体到受体的能量转移速率得到提升。尽管在光合作用中提出了其重要性，但尚未有直接的实验检测到超级转移，因为在生物或分子系统中，无法通过开关离域化来评估其对能量传输的影响。在这里，我们展示了可以利用基于超导电路的量子设备直接观测超级转移。工程设备所提供的可编程性和控制能力将允许量子态的可控离域化，从而完全调节超级转移。我们的超级转移工程指南可以为未来量子增强型光捕获器的设计提供参考。 显示英文摘要

摘要： Collective behaviour of the components of a quantum system can significantly alter the rates of dynamical processes within the system. A paradigmatic collective effect is superradiance, the enhancement in the rate that radiation is emitted by a group of emitters relative to that emitted by independent emitters. Less studied are collective effects in energy transport, notably supertransfer, the enhancement of the rate of energy transfer from donors to acceptors due to delocalised excitations. Despite its proposed significance in photosynthesis, there has been no direct experimental detection of supertransfer because, in biological or molecular systems, delocalisation cannot be turned on and off to evaluate its effect on energy transfer. Here, we show that supertransfer could be directly observed using a quantum device based on a superconducting circuit. The programmability and control offered by an engineered device would allow controllable delocalisation of quantum states, giving full tunability over supertransfer. Our guidelines for engineering supertransfer could inform the design of future quantum-enhanced light harvesters.
