Quantum Phase Transition of Non-Hermitian Systems using Variational Quantum Techniques
arXiv:2501.17003
Abstract
The motivation for studying non-Hermitian systems and the role of -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.
