rqutils.paulis.l0_projector¶
- rqutils.paulis.l0_projector(reduced_dim, original_dim)¶
Return the vector that projects the components of original_dim decomposition onto lambda_0 of reduced_dim.
- Parameters
reduced_dim (
int) – Matrix dimension of the target subspace.original_dim (
int) – Matrix dimension of the full space.
- Return type
numpy.ndarray- Returns
Projection vector \(\vec{v}\) that gives \(\bar{\nu}_0 = \vec{v} \cdot \vec{\nu}\).
