“Quantum semiotics”

There is considerable excitement about how quantum technologies (computing, communication and sensing) could advance human well being.
But, are we held back because as Richard Feynman said [1]“I think I can safely say that nobody understands quantum mechanics”? One of our difficulties is that we cannot see quantum. We lack standard visualisation tools. Semiotics – the doctrine of signs – refers to our use of symbols to represent the real world. In physics, our symbols are mostly mathematical but also diagrammatic.
In this talk, I will review the visualisation tools we use in quantum optics and quantum computating, and where they fail. Finally, I will discuss ideas about how we might advance our toolkit in order to gain new insight.
