All-Microwave Multiqubit Gates
Guanqi Wang, Yao Song, Peng-Bo Li +1
Implementing high-fidelity multiqubit gates is critical for reducing circuit depth in near-term quantum processors and fault-tolerant architectures. However, realizing multiqubit i…
Robust CZ gate against flux line memory
Yao Song, Xiu-Hao Deng
High-fidelity CZ gates are central to superconducting quantum processors, but implementations based on flux tuning are still sensitive to pulse distortion. Conventional predistorti…
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…
Robust Quantum Gates against Correlated Noise in Integrated Quantum Chips
Kangyuan Yi, Yong-Ju Hai, Kai Luo +9
As quantum circuits become more integrated and complex, additional error sources that were previously insignificant start to emerge. Consequently, the fidelity of quantum gates ben…
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…
Optimizing quantum control pulses with complex constraints and few variables through Tensorflow
Yao Song, Junning Li, Yong-Ju Hai +2
Applying optimal control algorithms on realistic quantum systems confronts two key challenges: to efficiently adopt physical constraints in the optimization and to minimize the var…
Correcting correlated errors for quantum gates in multi-qubit systems using smooth pulse control
Xiu-Hao Deng, Yong-Ju Hai, Jun-Ning Li +1
In multi-qubit system, correlated errors subject to unwanted interactions with other qubits is one of the major obstacles for scaling up quantum computers to be applicable. We pres…
