Ground and Excited States from Ensemble Variational Principles
1 1
Lexin Ding, Cheng-Lin Hong, and Christian Schilling, Quantum 8, 1525 (2024). The extension of the Rayleigh-Ritz variational principle to ensemble states $\rho_{\mathbf{w}}\equiv\sum_k w_k |\Psi_k\rangle \langle\Psi_k|$ with fixed weights $w_k$ lies ultimately at the hear…

Gradients and frequency profiles of quantum re-uploading models
1 1
Alice Barthe and Adrián Pérez-Salinas, Quantum 8, 1523 (2024). Quantum re-uploading models have been extensively investigated as a form of machine learning within the context of variational quantum algorithms. Their trainability and expressivity are not…

Code stylometry vs formatting and minification
1 1
The automatic identification of code authors based on their programming styles—known as authorship attribution or code stylometry—has become possible in recent years thanks to improvements in machine learning-based techniques for author recognition. Once feasible at scale, code stylometry can be...
