Quantum Phase Transition of Non-Hermitian Systems using Variational Quantum Techniques

Year: 2025

Type: conference-paper

Abstract: The motivation for studying non-hermitian systems and the role of PT-symmetry is discussed. We investigate the use of a quantum algorithm to find the eigenvalues and eigenvectors of non-Hermitian Hamiltonians, with applications to quantum phase transitions. We use a recently proposed variational algorithm. The systems studied are the transverse Ising model with both a purely real and a purely complex transverse field.
