Chiral and non-chiral swift mode conversion near an exception point with dynamic adiabaticity engineering
Dong Wang, Wen-Xi Huang, Bo Zhou +7
The eigenvalue of a non-Hermitian Hamiltonian often forms a self-intersecting Riemann surface, leading to a unique mode conversion phenomenon when the Hamiltonian evolves along cer…
Fundamental Sensitivity Limits for non-Hermitian Quantum Sensors
Wenkui Ding, Xiaoguang Wang, Shu Chen
Considering non-Hermitian systems implemented by utilizing enlarged quantum systems, we determine the fundamental limits for the sensitivity of non-Hermitian sensors from the persp…
Relations between quantum metrology and criticality in general su(1, 1) systems
Rui Zhang, Wenkui Ding, Zhucheng Zhang +3
There is a prevalent effort to achieve quantum-enhanced metrology using criticality. However, the extent to which estimation precision is enhanced through criticality still needs f…
Lee-Yang zeros and quantum Fisher information matrix in a nonlinear system
Hong Tao, Yuguo Su, Xingyu Zhang +2
The distribution of Lee-Yang zeros not only matters in thermodynamics and quantum mechanics, but also in mathematics. Hereby we propose a nonlinear quantum toy model and discuss th…
Coherent-cluster-state generation in networks of degenerate optical parametric oscillators
Zheng-Yang Zhou, Clemens Gneiting, J. Q. You +1
Cluster states are versatile quantum resources and an essential building block for measurement-based quantum computing. The possibility to generate cluster states in specific syste…
