Module algorithms 

Advanced quantum algorithms built on the state-vector simulator.

Complementing the textbook oracle algorithms in crate::algorithm, this module collects modern matrix-arithmetic and dynamics primitives:

• qsvt — Quantum Signal Processing, the single-qubit core of Quantum Singular Value Transformation (Gilyén–Su–Low–Wiebe 2019).
• quantum_walk — discrete-time coined quantum walk on a cycle, exhibiting ballistic spreading (Aharonov 1993 / Kempe 2003).
• amplitude_estimation — Quantum Amplitude Estimation via QPE on the Grover amplitude operator (Brassard–Høyer–Mosca–Tapp 2002).
• vqls — Variational Quantum Linear Solver for A = Σ_l c_l P_l (Bravo-Prieto et al. 2019).
• iterative_qpe — single-ancilla iterative (Kitaev) phase estimation with feedback (Kitaev 1995 / Dobšíček 2007).
