Realization of decoherence-induced averaged symmetry-protected topological phases on quantum processors
Ruizhe Shen, Xue-Jia Yu, Ching Hua Lee
Symmetry-protected topological (SPT) phases are conventionally formulated for pure states protected by exact symmetries. In open quantum systems, however, decoherence generates mix…

Non-Hermitian topology driven by an identity term: An exactly solvable paradigm
Lingfang Li, Yating Wei, Yang Ruan +6
An identity term in the Hamiltonian is conventionally regarded as spectrally inert-it shifts energies but does not alter eigenstate topology. We show that under non-Hermitian skin…

High-fidelity realization of the AKLT state on a NISQ-era quantum processor
Tianqi Chen, Ruizhe Shen, Ching Hua Lee +1
The AKLT state is the ground state of an isotropic quantum Heisenberg spin- model. It exhibits an excitation gap and an exponentially decaying correlation function, with fractio…
