Quantum many-body mixed phase space revealed by hybrid feedback control
Hang Dong, Jie Ren, Andrew Hallam +9
The paper introduces a hybrid quantum‑classical feedback protocol that discovers and stabilizes long‑lived regular trajectories in a superconducting quantum processor, revealing a…
A superconducting surface-code processor with lattice-surgery logical operations
Yanzhe Wang, Fanhao Shen, Haipeng Xie +31
Fault-tolerant logical operations are fundamental for scalable quantum computation. Here, we report the experimental realization of lattice-surgery operations between a pair of dis…
Fock space prethermalization and time-crystalline order on a quantum processor
Zehang Bao, Zitian Zhu, Yang-Ren Liu +31
Periodically driven quantum many-body systems exhibit a wide variety of exotic nonequilibrium phenomena and provide a promising pathway for quantum applications. A fundamental chal…
SCAFFOLD-CEGIS: Preventing Latent Security Degradation in LLM-Driven Iterative Code Refinement
Yi Chen, Yun Bian, Haiquan Wang +2
The application of large language models to code generation has evolved from one-shot generation to iterative refinement, yet the evolution of security throughout iteration remains…
Combinatorial optimization enhanced by shallow quantum circuits with 104 superconducting qubits
Xuhao Zhu, Zuoheng Zou, Feitong Jin +31
A pivotal task for quantum computing is to speed up solving problems that are both classically intractable and practically valuable. Among these, combinatorial optimization problem…
Experimental realization of the bucket-brigade quantum random access memory
Fanhao Shen, Yujie Ji, Debin Xiang +20
Quantum random access memory (QRAM) enables efficient classical data access for quantum computers -- a prerequisite for many quantum algorithms to achieve quantum speedup. Despite…
