Roadmap on quantum nanotechnologies
2021
Quantum phenomena are typically observable at length and time scales smaller than those of our everyday experience, often involving individual particles or excitations. The past few decades have seen a revolution in the ability to structure matter at the nanoscale, and experiments at the single particle level have become commonplace. This has opened wide new avenues for exploring and harnessing quantum mechanical effects in condensed matter. These quantum phenomena, in turn, have the potential to revolutionize the way we communicate, compute and probe the nanoscale world. Here, we review developments in key areas of quantum research in light of the nanotechnologies that enable them, with a …
Quantum Mechanics as a Semantic Problem
2018
Physics, like all science, is grown out of a desire to understand the world. However, modern physics with its mathematical form has become increasingly removed from the world of everyday experience and visual imagination. In quantum mechanics it is impossible to visualize the reality represented by the theory. All we have is a consistent mathematical structure. Although the theory works perfectly well instrumentally, the question remains, how can the mathematics of the theory impart understanding? If we look at mathematics as a language, we are faced with the semantic problem: how does the language of mathematics acquire meaning? In an attempt to answer this question, I study Derrida’s earl…
