class pygsti.baseobjs.errorgenbasis.ElementaryErrorgenBasis

Bases: object

A basis for error-generator space defined by a set of elementary error generators.

Elements are ordered (have definite indices) and labeled. Intersection and union can be performed as a set.

class pygsti.baseobjs.errorgenbasis.ExplicitElementaryErrorgenBasis(state_space, labels, basis1q=None)

Bases: ElementaryErrorgenBasis

A basis for error-generator space defined by a set of elementary error generators.

Parameters

label

ok_if_missingbool

If True, then returns None instead of an integer when the given label is not present.

create_subbasis(must_overlap_with_these_sslbls)

Create a sub-basis of this basis by including only the elements that overlap the given support (state space labels)

Bases: ElementaryErrorgenBasis

Spanned by the elementary error generators of given type(s) (e.g. “Hamiltonian” and/or “other”) and with elements corresponding to a Basis, usually of Paulis.
