In this proposal, the necessary research on the photon momentum setup with reproducible and SI traceable framework of quantum electrical-based measurements via Planck’s constant is described. The basis is a setup that integrates two State-of-the-Art measurement principles together, Kibble balance (i.e. Planck Balance – PB2) and photon momentum, using a special co nfiguration of the multi-reflected laser beam from ultra-high reflective mirrors for achieving a force amplification effect. Besides serving as a research platform that enables to investigate several fundamental metrological (measurement methodology) questions and raising the bar of State-of-the-Art measurement principles to the next level, it is constructed on individual component level based on conventional measurement methods and commonly available cost-effective materials allowing to obtain practical benefits, e.g. as a standard metrology setup highly demanded by metrology institutes globally, an industrial system for improved high precision and high accuracy small mass, small force and high energy laser optical power measurements and instrumentation calibrations, etc. Much attention deserves the operational (measurement) range that separates the quantum and classical mechanical measurement domains where only the use of macroscopic quantum electrical phenomena like the Josephson effect, and Quantum Hall effect allows to obtain the smallest possible reproducible and SI traceable measurement quantities with acceptable relative measurement uncertainties. Therefore, with this DFG project, an important contribution is being made for the creation of the scientific-technical foundations and implementation of the link between quantum and classical mechanics. Translated in terms of optical power and force values, arguably, this range stands at the several µW up to about 1 W level for power and 10 µN (mg) down to 10 pN (ng) for forces. Hence, the proposed work addresses not yet practically realized frontiers of small force (range: 10 µN to 10 nN), mass (1 mg to 1 µg), and optical power (mW to 100 W) measurements using fundamentally new State-of-the-Art methodology in a reproducible and SI traceable manner. And thus, the main research and development effort of the current proposal is aiming toward forthcoming complete measurement uncertainty estimations. The goal is to identify the relative measurement uncertainty of photon momentum generated forces below 100 nN and achieve estimated uncertainty for 10 µN – <0.001 (<0.1%), 1 µN – 1%.

在这个建议中，光子动量设置的可重复性和SI可追溯的量子电为基础的测量框架通过普朗克常数的必要研究进行了描述。其基础是将两种最先进的测量原理，Kibble平衡（即Planck Balance -PB 2）和光子动量集成在一起的设置，使用来自超高反射镜的多次反射激光束的特殊配置来实现力放大效应。除了作为一个研究平台，使人们能够研究几个基本的问题，（测量方法）问题，并将最先进的测量原理提高到一个新的水平，它是基于传统的测量方法和通常可用的成本效益材料在单个组件水平上构建的，可以获得实际利益，例如作为全球计量机构高度要求的标准计量设置，用于改进的高精度和高准确度的小质量、小力和高能激光光功率测量和仪器校准的工业系统，#21453;多的注意力，值得操作。（测量）范围，其将量子和经典力学测量域分开，其中仅使用宏观量子电学现象，如约瑟夫森效应，和量子霍尔效应允许获得最小可能的可重复和SI可追溯的测量量，并具有可接受的相对测量不确定性因此，通过DFG项目，为创建科学技术基础和实现量子力学与经典力学之间的联系做出了重要贡献。转换为光功率和力值，可以说，这个范围代表了几μW到大约1 W的功率水平和10 μN（mg）到10 pN（ng）的力。因此，拟议的工作使用全新的最新技术解决了尚未实际实现的小力（范围：10 µN至10 nN）、质量（1 mg至1 µg）和光功率（mW至100 W）测量的前沿问题。最先进的方法以可重现和SI可追溯的方式。因此，当前提案的主要研究和开发工作旨在实现即将到来的完整测量不确定度估计。目标是确定低于100 nN的光子动量产生力的相对测量不确定度，并实现10 µN - <0.001（<0.1%），1 µN -1%的估计不确定度。
