Parent Hamiltonian and intrinsic phase transition in non-Hermitian photonic systems
Yuntao Xiao, Yuchen Guo, Xiaojian Huang +6
Non-Hermitian systems host phenomena absent in Hermitian physics, but realizing Hamiltonians with intrinsic non-Hermitian properties remains challenging. The theoretical method of…
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 Restored Adiabatic State Transfer in Time-Modulated Non-Hermitian Systems
Xiaowei Wang, Ievgen I. Arkhipov, Quan Lin +5
Exceptional points (EPs) have attracted extensive research interest due to their intriguing properties. One of the hallmarks of EP physics is that dynamically encircling the EPs in…
Experimental device-independent certification of indefinite causal order
Dengke Qu, Quan Lin, Lei Xiao +2
Understanding the physical world fundamentally relies on the assumption that events are temporally ordered, with past events serving as causes for future ones. However, quantum mec…
