Quantum metrology triangle experiments combine three quantum electrical effects (the Josephson effect, the quantum Hall effect and the single-electron transport effect) used in metrology. These experiments allow important fundamental consistency tests on the validity of commonly assumed relations between fundamental constants of nature and the quantum electrical effects. This paper reviews the history, results and the present status and perspectives of quantum metrology triangle experiments. It also reflects on the possible implications of results for the knowledge on fundamental constants and the quantum electrical effects. In terms of relative standard uncertainty, the best result currently achieved is nine parts in 10 7 , while the goal is to reduce the uncertainty down to below five parts in 10 7 in order to provide an impact on the adjustment of the physical constants’ values.

This book provides a unified overview of “modern physics” - combining its foundational pillars: relativity, quantum physics and gravity - and takes the reader on a tour of fundamental physics, through structural, historical and biographical perspectives. The book presents a “big picture” of physics, as well as its completion in terms of a new vision of the quantum theory of space, time, matter and energy. Chapters explore the overarching and unfinished structure of fundamental physics, defined via the three fundamental constants of physics (the velocity of light, the gravitational constant and the Planck constant). The book also celebrates the centenary of quantum mechanics, and the apparent conceptual conflict between quantum theory and the deepest theory of spacetime physics, Einstein’s general theory of relativity, and the resolution of that conflict in a new (“gravitized quantum”) view of the problem of quantum gravity. This book will be of interest to undergraduate and graduate students of physics, professional physicists and scientists from other disciplines, as well as a general audience of non-professionals interested in the topic. Key features: Presents a cohesive and accessible overview of fundamental physics and its worldview Intertwines historical and biographical perspectives with scientific aspects Discusses a timely and cutting-edge topic at the forefront of research and discussion
