An Iterative Dual-Channel Neural Quantum State Algorithm for Selected Configuration Interaction
Jen-Yu Chang, Yi-Chun Chang, Yu-Jui Lin +6
Accurately solving the electronic Schrödinger equation for strongly correlated systems remains a central challenge in quantum chemistry, where the exponential growth of configurat…
Lattice-quantile estimation of Ï and convex-region integrals from coined two-dimensional quantum walks
Jen-Yu Chang, En-Jui Kuo, Chih-Yu Chen +1
Monte Carlo integration is fundamentally limited by the M^(-1/2) rate that the Cramer-Rao bound imposes on any sample-mean estimator of an expectation value, regardless of how the…
Split-Head Quantum Generative Adversarial Network for Crystalline Material Discovery
Huan-Ming Chang, Jen-Yu Chang, Tsung-Wei Huang +1
The discovery of novel crystalline materials is a critical challenge in computational materials science, often limited by the spatial representation limitations and mode collapse t…
Scalable Quantum Molecular Generation via GPU-Accelerated Tensor-Network Simulation
Yu-Cheng Xiao, Jen-Yu Chang, Tzu-Ling Kuo +7
We propose Scalable Quantum Molecular Generation (SQMG), a variational quantum-circuit for sampling molecular graphs using chemical priors on atoms and bonds. SQMG assigns a fixed…
Quantum Parrondo Paradox via a Single Phase Defect Symmetry Breaking and Directed Transport
Jen-Yu Chang, Yun-Hsuan Chen, Gooi Zi Liang +2
Parrondo paradox describes the counterintuitive phenomenon in which alternating two individually losing games yields a winning outcome. Extending this effect to the quantum regime…
Meta-Learning for GPU-Accelerated Quantum Many-Body Problems
Yun-Hsuan Chen, Jen-Yu Chang, Tsung-Wei Huang +1
We explore the industrial and scientific applicability of the VQE-LSTM framework by integrating meta-learning with GPU accelerated quantum simulation using NVIDIA's CUDA-Q (CUDAQ)…
