Interference-Induced Suppression of Doublon Transport and Prethermalization in the Extended Bose-Hubbard Model
Zhen-Ting Bao, Kai Xu, Heng Fan
The coherent mobility of doublons, arising from second-order virtual dissociation-recombination processes, fundamentally limits their use as information carriers in the strongly in…
Mathieu Control of the Effective Coupling in Superconducting Qubits
Yi-Han Yu, Xin-Yi Li, Kai Xu +1
A common challenge in superconducting quantum circuits is the trade-off between strong coupling and computational subspace integrity. We present Mathieu control, which uses a non-r…
Hybrid Quantum-Classical Neural Networks for Few-Shot Credit Risk Assessment
Zheng-an Wang, Yanbo J. Wang, Jiachi Zhang +11
Quantum Machine Learning (QML) offers a new paradigm for addressing complex financial problems intractable for classical methods. This work specifically tackles the challenge of fe…
Tomography-assisted noisy quantum circuit simulator using matrix product density operators
Wei-guo Ma, Yun-Hao Shi, Kai Xu +1
In recent years, efficient quantum circuit simulations incorporating ideal noise assumptions have relied on tensor network simulators, particularly leveraging the matrix product de…
Quantum Avalanches in -preserving Interacting Ising Majorana Chain
Lv Zhang, Kai Xu, Heng Fan
Recent numerical works have revealed the instability of many-body localized (MBL) phase in disordered quantum many-body systems with finite system sizes and over finite timescales.…
Distributed Quantum Computation via Entanglement Forging and Teleportation
Tian-Ren Jin, Kai Xu, Heng Fan
Distributed quantum computation is a practical method for large-scale quantum computation on quantum processors with limited size. It can be realized by direct quantum channels in…
Noisy Probabilistic Error Cancellation and Generalized Physical Implementability
Tian-Ren Jin, Kai Xu, Yu-Ran Zhang +1
Decoherence severely limits the performance of quantum processors, posing challenges to reliable quantum computation. Probabilistic error cancellation, a quantum error mitigation m…
Dynamics of quantum coherence in many-body localized systems
Jin-Jun Chen, Kai Xu, Li-Hang Ren +2
We demonstrate that the dynamics of quantum coherence serves as an effective probe for identifying dephasing, which is a distinctive signature of many-body localization (MBL). Quan…
Recovery of damaged information via scrambling in indefinite casual order
Tian-Ren Jin, Tian-Ming Li, Zheng-An Wang +3
Scrambling prevents the access to local information with local operators and therefore can be used to protect quantum information from damage caused by local perturbations. Even th…
Purity-Assisted Zero-Noise Extrapolation for Quantum Error Mitigation
Tian-Ren Jin, Yun-Hao Shi, Zheng-An Wang +3
Quantum error mitigation aims to reduce errors in quantum systems and improve accuracy. Zero-noise extrapolation (ZNE) is a commonly used method, where noise is amplified, and the…
Accurate and Fast Compressed Video Captioning
Yaojie Shen, Xin Gu, Kai Xu +3
Existing video captioning approaches typically require to first sample video frames from a decoded video and then conduct a subsequent process (e.g., feature extraction and/or capt…
