Quantum gate verification and its application in property testing
Pei Zeng, You Zhou, Zhenhuan Liu · Physical Review Research · 2020
This paper establishes a general framework of verifying a unitary gate based on few rounds of state preparation and measurements. The authors study the efficiency and optimality of the verification strategies in both non-adversarial and adversarial scenario. Furthermore, they provide examples for the commonly-used quantum gates and show the application in channel property testing
