qpe(unitary: QCallable, phase: QNum) -> None

[Qmod Classiq-library function]

Implements the standard Quantum Phase Estimation (QPE) algorithm, which estimates the phase (eigenvalue) associated with an eigenstate of a given unitary operator \(U\).

Parameters:

Name	Type	Description	Default
unitary	QCallable	A callable representing the unitary operator \(U\), whose eigenvalue is to be estimated.	required
phase	QNum	The quantum variable that represents the estimated phase (eigenvalue), assuming initialized to zero.	required
