Chiral Entangled-State Generation through Dissipative Quantum Dynamics
Huixia Gao, Konghao Sun, Yiwen Han +6
Dissipation, though often detrimental to quantum entanglement, can be manipulated for the preparation of entangled states, wherein ingeniously designed quantum jump processes drive…
Observation of Braid-Protected Unpaired Exceptional Points
Kunkun Wang, J. Lukas K. König, Kang Yang +4
Spectral degeneracies (dubbed nodal points in momentum space) play fundamental roles in understanding exotic properties of light and matter. In lattice systems, unpaired band-struc…
Simulating Floquet non-Abelian topological insulator with photonic quantum walks
Quan Lin, Tianyu Li, Haiping Hu +2
Floquet non-Abelian topological phases emerge in periodically driven systems and exhibit properties that are absent in their Abelian or static counterparts. Dubbed the Floquet non-…
Photonic chiral state transfer near the Liouvillian exceptional point
Huixia Gao, Konghao Sun, Dengke Qu +4
As branch-point singularities of non-Hermitian matrices, the exceptional points (EPs) exhibit unique spectral topology and criticality, with intriguing dynamic consequences in non-…
Non-Hermitian sensing in the absence of exceptional points
Lei Xiao, Yaoming Chu, Quan Lin +4
Open systems possess unique potentials in high-precision sensing, yet the majority of previous studies rely on the spectral singularities known as exceptional points. Here we theor…
