- Regulatory compliance validation
- Performance attribution analysis

**Example**:
```bash
gemini-flow gemini quantum portfolio \
  --assets 10 \
  --risk-tolerance 0.15 \
  --target-return 0.12 \
  --qubits 20 \
  --demo
```

**Expected Results**:

  --basis-set "6-31G*" \
  --demo
```

**Expected Results**:

**Example**:
```bash
gemini-flow gemini quantum crypto-keys \
  --key-length 256 \
  --algorithm "AES-256"
```

**Expected Results**:
- **+99.9% entropy quality** vs. pseudo-random generators
- **Quantum-resistant security** against future attacks
- **True randomness** from quantum mechanical measurements
- **Eavesdropping detection** through entanglement

### 4. 🌍 Climate Modeling with Quantum Atmospheric Effects
