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…
Measuring Mixed-State Topological Invariant in Open Photonic Quantum Walk
Qin-Qin Wang, Xiao-Ye Xu, Yong-Jian Han +2
Pure-state manifestations of geometric phase are well established and have found applications across essentially all branches of physics, yet their generalization to mixed-state re…
High-fidelity realisation of CNOT gate in Majorana-based optical platform
Jia-Kun Li, Kai Sun, Ze-Yan Hao +7
We present the experimental realisation of a robust CNOT quantum gate using Majorana zero modes simulated on a photonic platform. Three Kitaev chains supporting Majorana zero modes…
A millisecond integrated quantum memory for photonic qubits
Yu-Ping Liu, Zhong-Wen Ou, Tian-Xiang Zhu +6
Quantum memories for light are essential building blocks for quantum repeaters and quantum networks. Integrated operations of quantum memories could enable scalable application wit…
