qdk_chemistry.algorithms.phase_estimation.standard_phase_estimation module

Standard (QFT-based) phase estimation implementation.

This module implements the standard quantum phase estimation algorithm using the inverse Quantum Fourier Transform (QFT), which measures all phase bits in parallel using multiple ancilla qubits.
