High-efficiency On-chip Quantum Photon Source in Modal Phase-matched Lithium Niobate Nanowaveguide
Xiao-Xu Fang, Hao-Yang Du, Xiuquan Zhang +3
Thin-film lithium niobate on insulator~(LNOI) emerges as a promising platform for integrated quantum photon source, enabling scalable on-chip quantum information processing. The mo…
Experimental single-copy distillation of quantumness from higher-dimensional entanglement
Xiao-Xu Fang, Gelo Noel M. Tabia, Kai-Siang Chen +2
Entanglement is at the heart of quantum theory and is responsible for various quantum-enabling technologies. In practice, during its preparation, storage, and distribution to the i…
Experimental Catalytic Amplification of Asymmetry
Chao Zhang, Xiao-Min Hu, Feng Ding +6
The manipulation and transformation of quantum resources are key parts of quantum mechanics. Among them, asymmetry is one of the most useful operational resources, which is widely…
Efficient simulation of inhomogeneously correlated systems using block interaction product states
Yifan Cheng, Zhaoxuan Xie, Xiaoyu Xie +1
The strength of DMRG lies in its treatment of identical sites that are energetically degenerate and spatially similar. However, this becomes a drawback when applied to quantum chem…
Quantum decoherence dynamics in stochastically fluctuating environments
Xiangji Cai, Yanyan Feng, Jing Ren +2
We theoretically study the decoherence of a two-level quantum system coupled to noisy environments exhibiting linear and quadratic fluctuations within the framework of a stochastic…
Protecting entanglement witnesses with randomized measurements
Jing-Tao Qiu, Wei-Jie Jiang, Xiao-Dong Yu
Entanglement is one of the most prominent features of quantum mechanics and serves as an essential resource in quantum information science. Therefore, the certification of entangle…
