Efficient verification of quantum gates with local operations
Huangjun Zhu, Haoyu Zhang
Efficient verification of the functioning of quantum devices is a key to the development of quantum technologies, but is a daunting task as the system size increases. Here we propo…
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…
General framework for verifying pure quantum states in the adversarial scenario
Huangjun Zhu, Masahito Hayashi
Bipartite and multipartite entangled states are of central interest in quantum information processing and foundational studies. Efficient verification of these states, especially i…
Efficient Verification of Pure Quantum States in the Adversarial Scenario
Huangjun Zhu, Masahito Hayashi
Efficient verification of pure quantum states in the adversarial scenario is crucial to many applications in quantum information processing, such as blind measurement-based quantum…
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 Dicke states
Ye-Chao Liu, Xiao-Dong Yu, Jiangwei Shang +2
Among various multipartite entangled states, Dicke states stand out because their entanglement is maximally persistent and robust under particle losses. Although much attention has…
