The Weyl calculus is a means of constructing functions of a system of hermitian operators which do not necessarily commute with each other. This note gives a new proof of a formula, due to E. Nelson, ...

Simulation of non-Hermitian quantum mechanics using a quantum computer goes beyond centuries old conventions. Aalto researchers have used an IBM quantum computer to explore an overlooked area of ...
