Experimental Masking of Real Quantum States
Rui-Qi Zhang, Zhibo Hou, Zihao Li +4
Masking of quantum information is a way of hiding information in correlations such that no information is accessible to any local observer. Although the set of all quantum states a…
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…
Implementation of generalized measurements on a qudit via quantum walks
Zihao Li, Haoyu Zhang, Huangjun Zhu
Quantum measurements play a fundamental role in quantum mechanics and quantum information processing, but it is not easy to implement generalized measurements, the most powerful me…
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…
