RIA: Quantum Control of Light Generation in Mesoscopic Heterojunctions

半导体结构中光子产生过程的量子控制从基本和实际的观点来看都是很有意义的。本论文的目标是研究发光介观半导体异质结中量子控制和噪声抑制的基本限制。这项拟议的研究将强调产生预示着单光子状态，这代表了光产生的量子控制的最终极限。使用半经典分析，主要研究者已经预测，可以通过利用介观半导体中电子和空穴注入的库仑阻塞来实现光子发射时间的严格调节。在理论上，拟议的工作的重点将是新开发的量子Monte Carlo波函数方法耗散电子动力学在半导体及其应用的量子分析预示单光子态的产生。同时也将进行旨在调节介观P-I-I-N量子阱结构中光子产生过程的实验工作。可以预见的是，预示单光子态的新特性将发现许多应用，其中包括在单光子水平上的可靠信息编码和无噪声放大。***

9409633 Imamoglu The quantum control of photon generation processes in semiconductor stuctures is of substantial interest both from a fundamental and a practical point of view. The goal of the proposed work is to investigate the fundamental limits to quantum control and noise suppression in light emitting mesoscopic semiconductor heterojunctions. This proposed research will emphasize the generation of heralded single-photon states, which represent the ultimate limit in the quantum control of light generation. Using a semi-classical analysis, the principal investigator has already predicted that strict regulation of the photon emission times can be achieved by utilizing the Coulomb blockade of electron and hole injection in mesoscopic semiconductors. Theoretically, the emphasis of the proposed work would be on the newly developed quantum Monte Carlo wave-function approach to dissipative electron dynamics in semiconductors and its application to the quantum analysis of heralded single-photon state generation. The experimental work aimed at the regulation of the photon generation process in mesoscoptic P - I - i - I - N quantum well structures will also be pursued concurrently. It is anticipated that the novel features of heralded single-photon states will find many applications, which include reliable information encoding at the single-photon level and noise-free amplification. ***
