Module quantum_counting

Quantum Counting and Amplitude Estimation

This module implements quantum counting and amplitude estimation algorithms, which are key components for many quantum algorithms including Shor’s algorithm and quantum database search.

TODO: The current implementations are simplified versions. Full implementations would require:

• Proper controlled unitary implementations
• Full QFT and inverse QFT
• Better phase extraction from measurement results
• Integration with circuit builder for more complex operations
