Multipartite quantum resource distillation through local measurement programs
Yan Wang, Shao-Qi Lin, Xi-Nuo Tao +6
Distributed quantum resources in practical multi-user quantum networks are inevitably degraded by environmental noise, channel loss, and device-induced imperfections. To address th…
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…
Experimental Certification of Quantum Measurements with Maximally Mixed States
Jia-He Liang, Ze-Yan Hao, Jia-Kun Li +6
So far, certifying quantum devices from their input-output statistics, under minimal assumptions, required the preparation of specific pure quantum states. Recently, Xu et al. [Phy…
Optical demonstration of quantum fault-tolerant threshold
Kai Sun, Jin-Shi Xu, Xiao-Ye Xu +3
A major challenge in practical quantum computation is the ineludible errors caused by the interaction of quantum systems with their environment. Fault-tolerant schemes, in which lo…
Experimental observation of anomalous weak value without post-selection
Mu Yang, Qiang Li, Zheng-Hao Liu +5
Weak measurement has been shown to play important roles in the investigation of both fundamental and practical problems. Anomalous weak values are generally believed to be observed…
