Abstract In this paper, we first study the solution to linear matrix inequality AXB + (AXB)* ⩾ (>, ⩽, <) C when the matrix G = (A B*) is full row rank, where C is a Hermitian matrix. Furthermore, for ...

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.

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 ...
