Utility functions for working with Basis objects

Functions

basis_element_labels(basis, dim)	Get a list of short labels corresponding to to the elements of the described basis.
basis_longname(basis)	Get the "long name" for a particular basis, which is typically used in reports, etc.
basis_matrices(name_or_basis, dim[, sparse])	Get the elements of the specified basis-type which spans the density-matrix space given by dim.
change_basis(mx, from_basis, to_basis[, ...])	Convert a operation matrix from one basis of a density matrix space to another.
create_basis_for_matrix(mx, basis)	Construct a Basis object with type given by basis and dimension appropriate for transforming mx.
create_basis_pair(mx, from_basis, to_basis)	Constructs bases from transforming mx between two basis names.
flexible_change_basis(mx, start_basis, end_basis)	Change mx from start_basis to end_basis allowing embedding expansion and contraction if needed.
is_sparse_basis(name_or_basis)	Whether a basis contains sparse matrices.
resize_mx(mx[, dim_or_block_dims, resize])	Wrapper for resize_std_mx(), that manipulates mx to be in another basis.
resize_std_mx(mx, resize, std_basis_1, ...)	Change the basis of mx to a potentially larger or smaller 'std'-type basis given by std_basis_2.
state_to_pauli_density_vec(state_vec)	Convert a single qubit state vector into a Liouville vector in the Pauli basis.
state_to_stdmx(state_vec)	Convert a state vector into a density matrix.
stdmx_to_vec(m, basis)	Convert a matrix in the standard basis to a vector in the Pauli basis.
vec_to_stdmx(v, basis[, keep_complex])	Convert a vector in this basis to a matrix in the standard basis.
