The super-KMS property of functionals on a quantum algebra is investigated. It is known that these functionals define entire cyclic cocycles. The authors study stability of this structure under deformations. They define an index of a super-derivation on the quantum algebra, relative to any super-KMS functional and prove that the index is invariant under the deformations.
