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.

这项由跨学科科学与工程高级研究(RAISE)颁发的关于量子系统转型进展(TAQS)计划的奖项支持俄勒冈大学的Michael Raymer、Andrew Marcus和Brian Smith教授的合作工作，以展示在使用光的量子力学状态检测远程对象和电子耦合分子光谱方面实验改进的性能。依赖于内在量子力学效应的非线性光学光谱学和计量学的进展引起了化学、物理和工程界的广泛科学兴趣。如此发展的方法和研究将创造新的机会，可以用于不断扩大的量子信息科学跨学科领域。得到支持的研究将促进在国际会议和讲习班上传播成果，所开发的工具将随时提供给科学界。这三个专业人员将在拟议工作的所有方面进行合作，并将共同为从事该项目的博士生提供建议。俄勒冈州光学、分子和量子科学中心的一个跨化学、物理学和工程学的跨学科团队将进行实验，以证明在时频域中类似爱因斯坦-珀多尔斯基-罗森(EPR)的光子纠缠可以在光谱学和计量学中提供显著的量子优势。时频纠缠光子对(EPP)在时间上是紧密相关的，而在频率上是反相关的，因此光子对的能量之和是明确定义的。当使用光子符合事件时，这种光的量子态提供了绕过经典傅里叶时间带宽限制的能力，无论是在标准量子光学中的探测中，还是在分子络合物的双光子激发中，如在非线性光谱学中。这项研究将在计量学和非线性光谱学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(检测对象的存在或不存在)；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)双光子干涉非线性光谱学；以及4)纠缠光子对2D荧光光谱学。统一这四个方案的共同点是使用了由自发参数下转换(SPDC)产生的宽带(多光谱模式)、时频EPP，以及利用量子干涉的干涉仪配置。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
