Enhancement of signal-to-noise ratio at a high-order exceptional point of coherent perfect absorption
Zi-Qi Wang, Yi-Ming Sun, Yao-Dong Hu +4
Exceptional points (EPs) in non-Hermitian systems offer a remarkably strong response to weak perturbations, but the nonorthogonal nature of the corresponding eigenvectors causes no…
Strong coupling between a single-photon and a two-photon Fock state
Shuai-Peng Wang, Alberto Mercurio, Alessandro Ridolfo +9
The realization of strong nonlinear coupling between single photons has been a long-standing goal in quantum optics and quantum information science, promising wide impact applicati…
Frustration Elimination and Excited State Search in Coherent Ising Machines
Zheng-Yang Zhou, Clemens Gneiting, J. Q. You +1
Frustration, that is, the impossibility of satisfying the energetic preferences between all spin pairs simultaneously, underlies the complexity of many fundamental properties in sp…
Exploring Dynamics of Open Quantum Systems in Naturally Inaccessible Regimes
Xu-Ke Gu, Li-Zhou Tan, Franco Nori +1
Markovian open quantum systems are governed by the Lindblad master equation where the dissipation contains two parts, i.e., the anti-Hermitian operator and the quantum jumps, which…
