论文摘要
我们研究了由直流电流诱导的非邻苯烯等离激元偏振子介导的纠缠。非置换系统非常适合增强，控制和保存纠缠，这是由于单向束样波传播的潜力，即有效地将光子从一个发射极传输到另一个发射极。使用量子主方程和三维绿色功能分析，我们研究了一个由两个两级发射器组成的系统，这些系统通过电流诱导的石墨烯波导的非临界等离子等离子体模式来主要相互作用。我们将同时发生作为纠缠的量度。我们表明，非肾石墨烯等离激子极性子是产生和介导同意的有前途的候选者，在这种情况下，表明对真空的纠缠具有良好的增强和控制，这对纠缠作为量子资源的广泛应用是有益的。我们相信我们的发现有助于量子设备的开发，从而在两级系统之间实现了有效且可调的纠缠，这是量子技术的核心目标。
We investigate entanglement mediated by DC current induced nonreciprocal graphene plasmon polaritons. Nonreciprocal systems are ideal for the enhancement, control, and preservation of entanglement due to the potential for unidirectional beam-like wave propagation, i.e., efficiently transporting photons from one emitter to another. Using a quantum master equation and three-dimensional Green's function analysis, we investigate a system consisting of two two-level emitters dominantly interacting via electric current induced nonreciprocal plasmonic modes of a graphene waveguide. We use concurrence as a measure of entanglement. We show that nonreciprocal graphene plasmon polaritons are a promising candidate to generate and mediate concurrence, where it is shown that there is good enhancement and control of entanglement over vacuum, which is beneficial for the broad applications of entanglement as a quantum resource. We believe our findings contribute to the development of quantum devices, enabling efficient and tunable entanglement between two-level systems, which is a central goal in quantum technologies.
