Universal Robust Quantum Gates via Doubly Geometric Control
Hai Xu, Tao Chen, Junkai Zeng +5
Geometric quantum computation offers a potential route to fault-tolerant quantum information processing by exploiting the global nature of geometric phases. However, achieving cont…
Geometric correspondence of noisy quantum dynamics and universal robust quantum gates
Yong-Ju Hai, Junning Li, Junkai Zeng +1
Quantum information processing faces a significant hurdle: noise. Different noise sources induce varying errors in quantum operations depending on the underlying dynamics. To gain…
Smolyak algorithm assisted robust control for quantum systems with uncertainties
Zigui Zhang, Zibo Miao, Xiu-Hao Deng
Efficient and systematic numerical methods for robust control design are crucial in quantum systems due to inevitable uncertainties or disturbances. We propose a novel approach tha…
Enhanced Quantum Signal Control and Sensing Under Multicolored Noise via Generalized Filter Function Framework
Zhi-Da Zhang, Yao Song, Wen-Zheng Dong +1
We introduce a generalized filter-function framework that treats noise coupling strength as a tunable control parameter, enabling target noise suppression across user-defined frequ…
