Variational Quantum Models Underperform Classical Time-Series Forecasting
|
5.2
An arXiv preprint (v2 submitted Jan. 9, 2026) benchmarks variational quantum machine learning algorithms against classical models for time series forecasting. The authors evaluate models on three chaotic systems across 27 prediction tasks with extensive hyperparameter tuning, finding that quantum models often fail to match accuracy of simple classical counterparts. The study analyzes model-complexity trade-offs and practical limitations of variational quantum approaches.
Scoring Rationale
Comprehensive benchmarking across 27 tasks gives practical insight, but results derive from an arXiv preprint without peer review.
