项目摘要

Classical physics underpins many of the technological advances in computers, optical communications, and mobile devices that have made profound impacts in daily life, the economy, and society. However, as technology pushes forward, following Moore's law in computer engineering, it is gradually reaching limits where classical physics will no longer suffice. At this point, electrical and optical engineers will need to use quantum physics, which, up to the end of 20th century, had been mostly the subject of fundamental study. A key component for quantum technologies will be the ability to engineer quantum states of light, or photons. This research project will address the problem of quantum state engineering by exploring new ways to control the shape of single-photon quantum states using quantum interference. Because single-photon states are a basic building block for quantum technologies, this project will support the development of practical and versatile quantum devices for applications such as quantum information processing. The table-top experiments in this project are also an ideal platform for training and preparing next generation quantum physicists. Undergraduate students and graduate students will be involved in this research program. This project will deepen their understanding of quantum physics, which in turn will promote further applications using quantum interference techniques.Photon indistinguishability is essential to achieve complete quantum interference, which is the key in many protocols in optical quantum information processing with linear optical elements. The achievement of photon indistinguishability in experiments is through mode matching of photon states. While spatial modes of optical fields are relatively easy to manage, the temporal modes are much more complicated, especially for ultra-short pulses. In this research program, this team will employ a recently developed nonlinear quantum interferometric technique to achieve custom engineering of the spectral and temporal modes of the quantum states produced from ultra-fast nonlinear optical interactions. The essence of the technique is in the manipulation of the spectral phase shift that controls the nonlinear interaction via quantum interference and leads to interference filtering and eventually engineering of the spectral profiles of the output states for single mode operation. This team will implement the technique experimentally and demonstrate its effectiveness with a multi-photon interference experiment to achieve the efficient production of transform-limited single-photon states in single modes. Quantum state engineering is important for experimental implementations of quantum information protocols. It can be used to tailor the temporal modes of the optical fields to fit the experimental requirement and thus has very practical significance in the study of quantum information processing. This investigation provides a new approach for quantum state engineering.This project is jointly funded by the Quantum Information Science (QIS) Program in the Physics Division in the Mathematical and Physical Sciences Directorate, and the Electronics, Photonics and Magnetic Devices (EPMD) Program in the Division of Electrical, Communications and Cyber Systems Division in the Engineering Directorate.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

经典物理学支撑着计算机、光通信和移动设备的许多技术进步，这些进步对日常生活、经济和社会产生了深远的影响。然而，随着技术的进步，在计算机工程中遵循摩尔定律，它逐渐达到了经典物理不再足够的极限。在这一点上，电气和光学工程师将需要使用量子物理学，直到20世纪末，它一直是基础研究的主要主题。量子技术的一个关键组成部分将是设计光或光子的量子态的能力。该研究项目将通过探索利用量子干涉控制单光子量子态形状的新方法来解决量子态工程问题。由于单光子态是量子技术的基本组成部分，因此该项目将支持用于量子信息处理等应用的实用和通用量子器件的开发。本项目的桌面实验也是培养和准备下一代量子物理学家的理想平台。本科生和研究生将参与这项研究计划。这个项目将加深他们对量子物理的理解，进而促进量子干涉技术的进一步应用。光子不可分辨性是实现完全量子干涉的必要条件，是利用线性光学元件进行光量子信息处理的关键协议。实验中光子不可分辨是通过光子态的模式匹配实现的。光场的空间模式相对容易管理，而时间模式则要复杂得多，特别是对于超短脉冲。在这个研究项目中，该团队将采用最近开发的非线性量子干涉技术来实现超快速非线性光学相互作用产生的量子态的光谱和时间模式的定制工程。该技术的本质是通过量子干涉控制光谱相移，从而控制非线性相互作用，并导致干涉滤波，最终实现单模操作输出态的光谱轮廓工程。该团队将通过实验实现该技术，并通过多光子干涉实验证明其有效性，以实现在单模下有效地产生变换有限的单光子态。量子态工程对于量子信息协议的实验实现具有重要意义。它可以用来调整光场的时间模式以适应实验要求，因此在量子信息处理的研究中具有非常实际的意义。这项研究为量子态工程提供了新的途径。该项目由数学和物理科学理事会物理部的量子信息科学（QIS）计划和工程理事会电气、通信和网络系统部的电子、光子学和磁性器件（EPMD）计划共同资助。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
