QuantiSpect: A Structure-Aware Lightweight 3D CNN Pre-Decoder for Scalable Surface Code Quantum Error Correction
Pan Gao, Xu-Sheng Xu, Ji-Ze Han +7
Real-time decoding is a critical bottleneck for large-scale fault-tolerant quantum computing. AI-based neural pre-decoders locally correct most physical errors before passing resid…
Trainable Quantum Channels as Computational Primitives for Quantum Learning
Jingwei Wen, Runqing Zhang, Ling Qian +6
Variational quantum learning is traditionally constrained to unitary dynamics, often treating quantum channels as detrimental noise. In this work, we reformulate the quantum channe…

Yusheng Zhao, Han Wang, Xin Liu +10
Quantum control is essential for quantum information science and technology, yet designing high-fidelity control protocols remains challenging due to complex optimization landscape…
Robust and High-Fidelity Controlled Two-Qubit Gates via Asymmetric Parallel Resonant Excitation
Licheng Lin, Jize Han, Peng Zhu +4
Implementing high-fidelity controlled two-qubit gates in dipole-dipole interacting systems, such as rare-earth-ion crystals, in hindered by spectral inhomogeneity and weak coupling…
Scalable high-fidelity and near-deterministic preparation of large photon-number states
Mo Xiong, Jize Han, Chuanzhen Cao +3
The scalable preparation of large photon-number (Fock) states is a long-standing frontier in quantum science, with direct implications for quantum metrology and bosonic quantum inf…
Robust Non-Adiabatic Holonomic Gating in Qutrits via Inverse-Engineered Pulse Shaping and Error Compensation
Jie Lu, Jie-Dong Huang, Yang Qian +3
Systematic control errors, specifically Rabi frequency fluctuations and frequency detuning, constitute a primary bottleneck for high-fidelity quantum gates across leading platforms…
