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…
