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. ***

9409633 Imamoglu 从基础和实践的角度来看，半导体结构中光子生成过程的量子控制都具有重大意义。拟议工作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单光子态的产生，这代表了光产生的量子控制的最终极限。通过半经典分析，主要研究人员已经预测，可以通过利用介观半导体中电子和空穴注入的库仑封锁来实现对光子发射时间的严格调节。从理论上讲，拟议工作的重点是新开发的量子蒙特卡罗波函数方法，用于半导体中的耗散电子动力学及其在预示单光子态生成的量子分析中的应用。介观P-I-i-I-N量子阱结构中光子产生过程调控的实验工作也将同时进行。预计单光子态的新颖特征将有许多应用，其中包括单光子水平的可靠信息编码和无噪声放大。 ***
