Dynamically preparing robust Bell states by time-boundary engineering
Jia-Nan Wu, Bingsuo Zou, Guojun Jin +1
Quantum entanglement is essential for modern quantum information processing. Entanglement gates convert initially non-entangled states into entangled ones by applying time-dependen…
Machine-Learning Insights into the Entanglement-trainability Correlation of Parameterized Quantum Circuits
Shikun Zhang, Yang Zhou, Zheng Qin +4
Variational quantum algorithms (VQAs) have emerged as the leading strategy to obtain quantum advantage on the current noisy intermediate-scale devices. However, their entanglement-…
Diffusion-Enhanced Optimization of Variational Quantum Eigensolver for General Hamiltonians
Shikun Zhang, Zheng Qin, Yongyou Zhang +4
Variational quantum algorithms (VQAs) have emerged as a promising approach for achieving quantum advantage on current noisy intermediate-scale quantum devices. However, their large…
Amortized Variational Inference for Deep Gaussian Processes
Qiuxian Meng, Yongyou Zhang
Gaussian processes (GPs) are Bayesian nonparametric models for function approximation with principled predictive uncertainty estimates. Deep Gaussian processes (DGPs) are multilaye…
