ButterflyNet2D: Bridging Classical Methods and Neural Network Methods in Image Processing
Gengzhi Yang, Yingzhou Li
Both classical Fourier transform-based methods and neural network methods are widely used in image processing tasks. The former has better interpretability, whereas the latter ofte…
Hamiltonian transformation for accurate and efficient band structure interpolation
Kai Wu, Yingzhou Li, Wentiao Wu +3
Electronic band structure is a cornerstone of condensed matter physics and materials science. Conventional methods like Wannier interpolation (WI), which are commonly used to inter…
Analysis of Error Propagation in Quantum Computers
Ziang Yu, Yingzhou Li
Most quantum gate errors can be characterized by two error models, namely the probabilistic error model and the Kraus error model. We proved that for a quantum circuit with either…
Improving the Accuracy of Variational Quantum Eigensolvers With Fewer Qubits Using Orbital Optimization
Joel Bierman, Yingzhou Li, Jianfeng Lu
Near-term quantum computers will be limited in the number of qubits on which they can process information as well as the depth of the circuits that they can coherently carry out. T…
SpecNet2: Orthogonalization-free spectral embedding by neural networks
Ziyu Chen, Yingzhou Li, Xiuyuan Cheng
Spectral methods which represent data points by eigenvectors of kernel matrices or graph Laplacian matrices have been a primary tool in unsupervised data analysis. In many applicat…
KSSOLV 2.0: An efficient MATLAB toolbox for solving the Kohn-Sham equations with plane-wave basis set
Shizhe Jiao, Zhenlin Zhang, Kai Wu +12
KSSOLV (Kohn-Sham Solver) is a MATLAB toolbox for performing Kohn-Sham density functional theory (DFT) calculations with a plane-wave basis set. KSSOLV 2.0 preserves the design fea…
Quantum Orbital Minimization Method for Excited States Calculation on Quantum Computer
Joel Bierman, Yingzhou Li, Jianfeng Lu
We propose a quantum-classical hybrid variational algorithm, the quantum orbital minimization method (qOMM), for obtaining the ground state and low-lying excited states of a Hermit…
