qrisp.gqsp.qsvt_angles#
- qsvt_angles(p: ArrayLike, parity: Literal['even', 'odd'] = 'odd') tuple[Array, Array][source]#
Computes the QSVT angles for a given polynomial.
- Parameters:
- pArrayLike
1-D array containing the polynomial coefficients in Chebyshev basis, ordered from lowest order term to highest.
- parityLiteral[“even”, “odd”]
The structural parity of the target polynomial (‘even’ or ‘odd’). Defaults to ‘odd’. Must be known at compile time for JAX tracing.
- Returns:
- anglesArray
1-D array of angles \((\phi_0,\dotsc,\phi_d)\).
- alphaArray
The scalar scaling factor as 0-D array.
Notes
The resulting angles correspond to a rescaled version of the input polynomial.
