摘要:

相干量子反馈控制(CQFC)作为精确操纵复杂量子系统动力学的新范式的出现,导致了有效的理论建模和仿真工具的发展,并为新的实际实现开辟了途径。这项工作探讨了集成硅光子学平台实现可扩展的CQFC网络的适用性。如果被证明是成功的,这些网络的片上实现将为电信波长的自主量子信息处理设备和超低功率光学处理系统提供可扩展和高效的纳米光子组件。我们分析了CQFC应用的硅光子学平台的优势,并确定了理论形式和实验实现的关键挑战。特别是,我们确定具体的扩展理论CQFC框架(这是最初开发的批量光学实现铭记),需要使其完全适用于线性和非线性集成光学网络的建模。我们还报告了一个初步的实验,研究了两个耦合腔的原位可控硅纳米光子网络的性能,并使用CQFC形式主义分析该设备的属性的结果。

英文摘要:

The emergence of coherent quantum feedback control (CQFC) as a new paradigm for precise manipulation of dynamics of complex quantum systems has led to the development of efficient theoretical modeling and simulation tools and opened avenues for new practical implementations. This work explores the applicability of the integrated silicon photonics platform for implementing scalable CQFC networks. If proven successful, on-chip implementations of these networks would provide scalable and efficient nanophotonic components for autonomous quantum information processing devices and ultra-low-power optical processing systems at telecommunications wavelengths. We analyze the strengths of the silicon photonics platform for CQFC applications and identify the key challenges to both the theoretical formalism and experimental implementations. In particular, we determine specific extensions to the theoretical CQFC framework (which was originally developed with bulk-optics implementations in mind), required to make it fully applicable to modeling of linear and nonlinear integrated optics networks. We also report the results of a preliminary experiment that studied the performance of an in situ controllable silicon nanophotonic network of two coupled cavities and analyze the properties of this device using the CQFC formalism.
