Quantum mechanics has a concept called a “wave function.” It’s incredibly important because it holds all the measurable information about a particle (or group of particles) within it. In practice, the ...

Quantum mechanics is a pillar of modern science and technology, and has benefited the human society for a century. The wave function, also known as the quantum state, is the description of a quantum ...

The fuzzy quantum shape that describes the speed or location of a single particle, its wave function, has now been directly measured in the laboratory, giving this mathematical concept a small dose of ...

Most interpretations of quantum mechanics have taken non-locality – “spooky action at a distance” – as a brute fact about the way the world is. But there is another way. Take seriously quantum ...

It underpins the whole theory of quantum mechanics, but does it exist? For nearly a century physicists have argued about whether the wave function is a real part of the world or just a mathematical ...

Prolate spheroidal wave functions (PSWFs) and their discrete counterparts – the discrete prolate spheroidal sequences (DPSSs) – have emerged as essential tools in the analysis of band‐limited ...
