# ❌ WRONG - Generic database code
conn = BioQL.connect('localhost')
cursor = conn.cursor()
cursor.execute("SELECT * FROM quantum_states")
```

**DeepSeek Fine-tuned Output**:
```python
# ✅ CORRECT - Proper BioQL syntax
from bioql import quantum

result = quantum("Create Bell state", backend="simulator", shots=1024)
