LLM-Driven Cross-Paradigm Design for Quantum Optimal Control
Yu-Qin Chen, Shi-Xin Zhang
Quantum optimal control (QOC) underpins adiabatic quantum computation, quantum annealing, and quantum state engineering, yet practical deployment is fundamentally bottlenecked by s…
Revealing Entanglement-Growth Mechanisms through the Magic Barrier
Lv Zhang, Shi-Xin Zhang, Heng Fan +1
Quantum entanglement and magic are complementary resources underlying quantum computational advantage, yet their dynamical relation in many-body systems remains poorly understood.…
Entanglement Growth from Entangled States: A Unified Perspective on Entanglement Generation and Transport
Chun-Yue Zhang, Zi-Xiang Li, Shi-Xin Zhang
Studies of entanglement dynamics in quantum many-body systems have focused largely on initial product states. Here, we investigate the far richer dynamics from initial entangled st…
ORBIT-Q: Dual-axis benchmarking of autonomous agents in scientific quantum programming
Shi-Xin Zhang, Yu-Qin Chen
Autonomous coding agents perform well on many conventional programming tasks, but scientific computing demands a rigorous validation paradigm that extends beyond simple functional…
Absence of poor local minima in matrix product states
Hao-Kai Zhang, Chenghong Zhu, Shuo Liu +2
Quantum circuits suffer from severe trainability issues: even shallow circuits are swamped with poor local minima. Yet matrix product states (MPS), which can be prepared by sequent…
Intrinsic preservation of plasticity in continual quantum learning
Yu-Qin Chen, Shi-Xin Zhang
Artificial intelligence in dynamic, real-world environments requires the capacity for continual learning. However, standard deep learning suffers from a fundamental issue: loss of…
