Projection measurement of the comb basis through free-electron-photon interactions
Zihang Zou, Feng-Xiao Sun, Yunquan Liu +1
Free electrons, driven by rapid advances in photon-induced near-field electron microscopy, have emerged as a promising platform for quantum information processing, including quantu…
Attosecond quantum spectroscopy with entangled photon pairs
Zijian Lyu, Fengxiao Sun, Sili Yi +6
Bright squeezed light from parametric down-conversion in the infrared (IR) frequency range has triggered the emergence of attosecond quantum optics -- a new research field at the i…
Observe novel tricritical phenomena in self-organized Fermi gas induced by higher order Fermi surface nesting
Yilun Xu, Feng-Xiao Sun, Qiongyi He
Cold atom systems in optical lattices have long been recognized as an ideal platform for bridging condense matter physics and quantum optics. Here, we investigate the 1D fermionic…
Foundation Model for Unified Characterization of Optical Quantum States
Xiaoting Gao, Yan Zhu, Feng-Xiao Sun +2
Machine learning methods have been used to infer specific properties of limited families of optical quantum states, but a unified model that predicts a broad range of properties fo…
Detection of non-Gaussian quantum correlations through measurement-after-interaction protocols
Jiajie Guo, Feng-Xiao Sun, Matteo Fadel +1
Additional state evolutions performed before measurement, also called measurement-after-interactions (MAI) protocols, have shown a great potential for increasing the sensitivity of…
Characterizing the Multipartite Entanglement Structure of Non-Gaussian Continuous-Variable States with a Single Evolution Operator
Mingsheng Tian, Xiaoting Gao, Boxuan Jing +4
Multipartite entanglement is an essential resource for quantum information tasks, but characterizing entanglement structures in continuous variable systems remains challenging, esp…
