We examine a two-parameter (ℏ,λ) deformation of the Poincaré algebra which is covariant under the action of SL q(2,C). When λ → 0 it yields the Poincaré algebra, while in the ℏ → 0 limit we recover the classical quadratic algebra discussed previously in Refs. 1 and 2. The analogues of the Pauli–Lubanski vector w and Casimirs p2 and w2 are found and a set of mutually commuting operators is constructed.
