Reinforcement-Learned Electric-Field Sensing with Asymmetrically Blockaded Rydberg Arrays
Shi-Qiang Qiao, Xue-Ke Song, Shi-Lei Su +2
We present a reinforcement learning-optimized Rydberg electrometer based on the asymmetric blockade effect and achieve high-sensitivity electric field sensing in Rydberg arrays. Mi…
Dynamical redistribution of quantum resources in tree-level Bhabha scattering
Zan Cao, Meng-Long Song, Xue-Ke Song +2
The fundamental interactions governed by quantum electrodynamics (QED) are intrinsically rich in quantum resources, yet how these resources dynamically redistribute during relativi…
Transducer leakage error suppression using invariant-based shortcut
Shi-Qiang Qiao, Zheng Shan, Xue-Ke Song +3
The paper proposes an invariant‑based shortcut control method to suppress transducer leakage errors in spin‑superconducting hybrid quantum systems, achieving over 99% fidelity for…
Quantifying and Probing Multipartite Entanglement via Minimum Entanglement Drop
Dong-Dong Dong, Xue-Ke Song, Liu Ye +1
Quantifying genuine multipartite entanglement remains a significant challenge. We propose a multipartite entanglement monotone defined by the minimum entanglement drop -- the reduc…
Universal photon blockade via two-photon light-matter interaction at chiral exceptional points
Hai-Tao Dong, Meng-Long Song, Si-Yu Zhang +3
The photon blockade (PB) effect is a hallmark non-classical phenomenon in quantum optics and finds important applications for building quantum sources, while the control of PB by t…
Genuine tripartite entanglement in Bhabha scattering with an entangled spectator particle
Zan Cao, Meng-Long Song, Xue-Ke Song +2
From the perspective of quantum information science, we investigate tree-level Bhabha scattering between an incident electron and a positron , where is initially entangl…
