For the non-Hermitian and positive semidefinite systems of linear equations, we derive necessary and sufficient conditions for guaranteeing the unconditional convergence of the preconditioned ...

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 ...

A research team has achieved a groundbreaking quantum simulation of the non-Hermitian skin effect in two dimensions using ultracold fermions, marking a significant advance in quantum physics research.
