Optimal verification of stabilizer states
Ninnat Dangniam, Yun-Guang Han, Huangjun Zhu
Statistical verification of a quantum state aims to certify whether a given unknown state is close to the target state with confidence. So far, sample-optimal verification protocol…
Verification of phased Dicke states
Zihao Li, Yun-Guang Han, Hao-Feng Sun +2
Dicke states are typical examples of quantum states with genuine multipartite entanglement. They are valuable resources in many quantum information processing tasks, including mult…
Optimal Verification of Greenberger-Horne-Zeilinger States
Zihao Li, Yun-Guang Han, Huangjun Zhu
We construct optimal protocols for verifying qubit and qudit GHZ states using local projective measurements. When the local dimension is a prime, an optimal protocol is constructed…
Efficient verification of bipartite pure states
Zihao Li, Yun-Guang Han, Huangjun Zhu
We propose practical and efficient protocols for verifying bipartite pure states for any finite dimension, which can also be applied to fidelity estimation. Our protocols are based…
Non-Markov property of afterpulsing effect in single-photon avalanche detector
Fang-Xiang Wang, Wei Chen, Ya-Ping Li +6
Single-photon avalanche photodiode(SPAD) has been widely used in researching of quantum optics. Afterpulsing effect, which is an intrinsic character of SPAD, affects the system per…
