There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability ...

Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct ...

Quantum state diffusion framework makes it possible to characterize quantum measurement in terms of entropy production ...

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 ...

Nearly a century after the development of quantum theories, a consensus has yet to emerge about what these theories tells us about ourselves and our places in the universe. Ney develops a framework — ...
