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…
Efficient learning of mixed-state tomography for photonic quantum walk
Qin-Qin Wang, Shaojun Dong, Xiao-Wei Li +7
Noise-enhanced applications in open quantum walk (QW) have recently seen a surge due to their ability to improve performance. However, verifying the success of open QW is challengi…
Photonic simulation of Majorana-based Jones polynomials
Jia-Kun Li, Kai Sun, Ze-Yan Hao +7
Jones polynomials were introduced as a tool to distinguish between topologically different links. Recently, they emerged as the central building block of topological quantum comput…
