项目摘要

This award in the Research Advanced by Interdisciplinary Science and Engineering (RAISE) on Transformational Advances in Quantum Systems (TAQS) program supports collaborative work by Professors Michael Raymer, Andrew Marcus and Brian Smith at the University of Oregon to demonstrate experimentally improved performance in the sensing of remote objects and the spectroscopy of electronically coupled molecules using quantum mechanical states of light. Advancements in nonlinear optical spectroscopy and metrology that rely on intrinsically quantum mechanical effects are of broad scientific interest to the chemistry, physics and engineering communities. The methods and research so developed will create new opportunities that may be utilized in the expanding interdisciplinary field of quantum information science. The supported research will facilitate the dissemination of results at international meetings and workshops, and the tools developed will be made readily available to the scientific community. The three PIs will collaborate on all aspects of the proposed work, and will co-advise the PhD students working on the projects. The students involved will thus enjoy a unique and broad exposure to research training that spans quantum optics, ultrafast molecular spectroscopy, and biophysics.An interdisciplinary team spanning chemistry, physics, and engineering in the Oregon Center for Optical, Molecular, and Quantum Science, will carry out experiments to demonstrate that Einstein-Podolsky-Rosen (EPR)-like entanglement of photons in the time-frequency domain can provide a significant quantum advantage in spectroscopy and metrology. Time-frequency entangled photon pairs (EPP) are tightly correlated in time while being anti-correlated in frequency, such that the sum of the energies of the photon pair is sharply defined. Such quantum states of light offer the ability to circumvent classical Fourier time-bandwidth limits when employing photon coincidence events, either in detection, as in standard quantum optics, or in two-photon excitation of molecular complexes, as in nonlinear spectroscopy. The research will investigate potential quantum advantages in the context of four related optical schemes in metrology and nonlinear spectroscopy: 1) Quantum illumination (sensing of an object's presence or absence); 2) Multi-parameter estimation of complementary parameters (e.g., estimating the distance and velocity of a reflecting object); 3) Two-photon interferometric nonlinear spectroscopy; and 4) Entangled photon-pair 2D fluorescence spectroscopy. The commonality that unifies the four schemes is the use of broad-band (multi-spectral-mode), time-frequency EPP produced by spontaneous parametric down-conversion (SPDC), coupled with interferometer configurations that exploit quantum interference.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.

跨学科科学与工程学（RAIS）在量子系统（TAQS）计划的变革性进步提前的研究中的这一奖项支持俄勒冈大学的教授Michael Raymer，Andrew Marcus和Brian Smith教授的合作工作，以证明使用量子量的远程对象和使用量子的电子光谱，以实验提高了远程对象的性能。依赖于本质上量子力学效应的非线性光谱和计量学的进步对化学，物理和工程社区具有广泛的科学意义。如此开发的方法和研究将创造新的机会，这些机会可以在不断扩大的量子信息科学跨学科领域中使用。支持的研究将有助于在国际会议和研讨会上传播结果，并将开发的工具很容易为科学界提供。这三个PI将在拟议工作的各个方面进行合作，并将共同介绍从事这些项目的博士生。因此，所参与的学生将享受独特而广泛的研究培训，该研究培训跨越量子光学，超快分子光谱和生物物理学。在俄勒冈州光学，分子和量子科学中，一个跨学科的团队跨越了俄勒冈州的化学，物理和工程中心，将表明einstein-Pododolsky-pododolsky-proponefience time time-eprefience-epr） - 域可以在光谱和计量学方面具有显着的量子优势。时频纠缠的光子对（EPP）在频率上抗相关时，时间紧密相关，从而明确定义了光子对的能量之和。这样的量子状态提供了在使用光子重合事件（如标准量子光学元件）或分子复合物的两光子激发中，如非线性光谱法所示，可以在检测中使用光子重合事件时规避经典的傅立叶时间带宽限制。该研究将在计量学和非线性光谱方面的四个相关光学方案的背景下研究潜在的量子优势：1）量子照明（感应物体的存在或不存在）； 2）互补参数的多参数估计（例如，估计反射对象的距离和速度）； 3）两光子干涉指定非线性光谱； 4）纠缠的光子对2D荧光光谱。统一四个方案的通用性是使用宽带（多光谱模式），由自发参数下转换（SPDC）产生的时频EPP（SPDC）产生的，以及干涉仪的配置，以及利用量子的奖励，反映了NSF的合法传教士和良好的依据。标准。
