Dozens of interpretations of quantum mechanics have been developed over the years. Most of them attempt to address what happens when an observation or measurement is made on a quantum system. The ...

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 ...

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 ...

The idea that the universe splits into multiple realities with every measurement has become an increasingly popular proposed solution to the mysteries of quantum mechanics. But this “many-worlds ...

From the vantage point of quantum physics, the universe may in some ways be fundamentally unknowable. In quantum physics, every object, such as an electron, is matched to a mathematical formula called ...

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 ...
