Benchmarking non-Clifford gates using only Pauli twirling group
Han Ye, Guoding Liu, Xiongfeng Ma
Quantum gate benchmarking is unavoidably influenced by state preparation and measurement errors. Randomized benchmarking addresses this challenge by employing group twirling to reg…
State complexity and phase identification in adaptive quantum circuits
Guoding Liu, Junjie Chen, Xiongfeng Ma
Adaptive quantum circuits, leveraging measurements and classical feedback, significantly expand the landscape of realizable quantum states compared to their non-adaptive counterpar…
Calibrating quantum gates up to 52 qubits in a superconducting processor
Daojin Fan, Guoding Liu, Shaowei Li +18
Benchmarking large-scale quantum gates, typically involving multiple native two-qubit and singlequbit gates, is crucial in quantum computing. Global fidelity, encompassing informat…
Optimizing Circuit Reusing and its Application in Randomized Benchmarking
Zhuo Chen, Guoding Liu, Xiongfeng Ma
Quantum learning tasks often leverage randomly sampled quantum circuits to characterize unknown systems. An efficient approach known as "circuit reusing," where each circuit is exe…
