Hybrid Architecture Patterns

Pattern A: Classical Backbone + Quantum Layer

Classical CNN/Transformer → Feature Extraction → Variational Quantum Circuit → Classification

• Classical layers handle feature extraction from high-dimensional data
• 4-8 qubit VQC captures quantum correlations in feature space
• Effective for medical imaging with limited quantum resources

Pattern B: Quantum-Enhanced Optimization

Classical Data → Quantum Encoding → QAOA/VQE Optimization → Classical Post-processing

• Used for drug discovery molecule optimization
• Quantum handles combinatorial search space
• Classical handles molecular dynamics simulation

Pattern C: Noise-Aware Quantum Pipeline

Input Data → Noise Modeling → Fourier Attenuation → VQC → Error Mitigation → Output

• Addresses label noise prevalent in medical datasets
• Three complementary noise-resilient mechanisms
• Critical for real-world clinical data quality

Pattern D: Temporal Encoder + VQC Feature Mixer

Historical Clinical Data → GRU/LSTM Temporal Encoder → Angle Projection → VQC → Prediction

• GRU encoder summarizes temporal observation window into latent representation
• Latent vectors projected to quantum rotation angles for VQC parameterization
• VQC acts as learnable non-linear feature mixer modeling cross-variable interactions
• Particularly effective for small-cohort clinical time series (ECG, PPG, SpO2, respiratory rate)
• Demonstrated greater robustness to noise and missing inputs vs classical-only baselines
• arXiv: 2603.08072 — Hybrid Quantum Neural Network for Multivariate Clinical Time Series Forecasting
