Tunable topological enhancement of covariant quantum Fisher information via non-Bloch skin effect in non-Hermitian SSH lattices
Qi-Cheng Wu, Yan-Hui Zhou, Tong Liu +2
The covariant quantum Fisher information (CQFI) has recently been established as the ultimate precision benchmark for pseudo-Hermitian sensors [Phys. Rev. Lett. 136, 080802 (2026)]…
Extension of Noether's theorem in PT-symmetric systems and its experimental demonstration in an optical setup
Q. C. Wu, J. L. Zhao, Y. L. Fang +4
Noether's theorem is one of the fundamental laws in physics, relating the symmetry of a physical system to its constant of motion and conservation law. On the other hand, there exi…
Quantum state discrimination in a PT-symmetric system
Dong-Xu Chen, Yu Zhang, Jun-Long Zhao +4
Nonorthogonal quantum state discrimination (QSD) plays an important role in quantum information and quantum communication. In addition, compared to Hermitian quantum systems, parit…
Experimental investigation of wave-particle duality relations in asymmetric beam interference
Dong-Xu Chen, Yu Zhang, Jun-Long Zhao +4
Wave-particle duality relations are fundamental for quantum physics. Previous experimental studies of duality relations mainly focus on the quadratic relation , based…
Entanglement Dynamics in Anti--Symmetric Systems
Yu-Liang Fang, Jun-Long Zhao, Dong-Xu Chen +5
In the past years, many efforts have been made to study various noteworthy phenomena in both parity-time () and anti-parity-time () symmetric systems.…
Experimental demonstration of coherence flow in - and anti--symmetric systems
Yu-Liang Fang, Jun-Long Zhao, Yu Zhang +5
Non-Hermitian parity-time () and anti-parity-time ()-symmetric systems exhibit novel quantum properties and have attracted increasing interest. Althoug…
