The objective of this research program is to develop a practical quantum measurement technology - attosecond-resolution quantum interferometry. The need for the highest possible resolution in optical interferometric measurements is increasing with modern trends in fiber sensing, optical device characterization, optical identification of folded-unfolded and engaged protein markers, biological imaging of tissue and brain, and in hundreds of other science and technology applications. The approach is based on the utilization of polarization- and frequency-entangled states of light accompanied by the non-classical effect of dispersion cancellation. This use of several mutually entangled variables (hyper-entanglement) will boost the resolution of numerous sensing applications. The goal is the development of quantum interferometry for group velocity delay evaluation that has two orders of magnitude better resolution than the best classical optical apparatus could achieve. Intellectual merit. The availability of quantum interferometry with attosecond resolution will be capable of revolutionizing optical measurement and sensing in multiple areas from telecommunication to biology. The project must go significantly beyond the current state-of-the-art, and will rely on an interdisciplinary approach at the intersection of quantum optics, material science, and optical measurement. Broader impacts. Novel scientific devices as well as environmental and biophotonics sensors always strive for greater resolution in order to reveal effects that are currently hidden from modern optical sensors. Quantum optics and quantum measurement are highly potent modern research fields, and the current project holds promise for attracting talented undergraduate and high-school students who are eager to join the development of future technological breakthroughs.

本研究计划的目标是发展一种实用的量子测量技术--阿秒分辨率量子干涉术。随着光纤传感、光学器件表征、折叠-展开和接合蛋白质标记物的光学识别、组织和大脑的生物成像以及数百种其他科学和技术应用的现代趋势，对光学干涉测量中尽可能高的分辨率的需求正在增加。该方法是基于利用偏振和频率纠缠态的光伴随着非经典效应的色散抵消。这种使用几个相互纠缠的变量（超纠缠）将提高许多传感应用的分辨率。我们的目标是发展量子干涉测量的群速度延迟的评估，有两个数量级更好的分辨率比最好的经典光学仪器可以实现。智力上的优点。 具有阿秒分辨率的量子干涉测量的可用性将能够在从电信到生物学的多个领域彻底改变光学测量和传感。 该项目必须大大超越目前的最先进水平，并将依赖于量子光学，材料科学和光学测量交叉的跨学科方法。更广泛的影响。 新的科学设备以及环境和生物光子传感器一直在努力提高分辨率，以揭示目前隐藏在现代光学传感器之外的效应。量子光学和量子测量是非常强大的现代研究领域，目前的项目有望吸引渴望加入未来技术突破发展的优秀本科生和高中生。
