Observation of quantum nonclassicality without freedom of choice in a minimal causal network
Ya Xiao, Yan-Xin Rong, Ran He +6
Quantum causal networks enable tests of nonclassicality beyond Bell nonlocality while relaxing some physically unwarranted assumptions. By relaxing the freedom-of-choice and spacel…
Loss and distinguishability effects in heralded entangled state generation with Gaussian resources
Yun-Long Cao, Xiao-Ye Xu, Wiwittawin Sukmas +2
The effects of optical loss and photon distinguishability on the heralded generation of entangled states based on Gaussian resources are quantitatively investigated. By incorporati…
Experimental detection of entanglement in multimode Gaussian states from high-order intensity correlation moments
Ze-Shan He, Yukuan Zhao, Hao-Shu Tian +4
Quantum universal invariants of a Gaussian state's covariance matrix, which can be derived from intensity correlation moments, have been adopted to characterize the entanglement pr…
Nonunitary Preparation of Nontrivial States from Trivial Regimes in Two-Dimensional Topological Insulators
Qin-Qin Wang, Xiao-Ye Xu, Chuan-Feng Li +1
While remarkable progress has been achieved in engineering nontrivial Hamiltonians across a wide range of physical platforms, preparing their corresponding nontrivial ground states…
Heralded entangled state generation enhanced by photon addition and subtraction
Yun-Long Cao, Xiao-Ye Xu, Chuan-Feng Li +1
We propose a heralded entanglement generation scheme based on Gaussian sources enhanced by photon addition and subtraction operations. By combining single-mode squeezing, linear in…
3D imaging of the biphoton spatiotemporal wave packet
Yang Xue, Ze-Shan He, Hao-Shu Tian +6
Photons are among the most important carriers of quantum information owing to their rich degrees of freedom (DoFs), including various spatiotemporal structures. The ability to char…
