  We develop a charge-parity-time (CPT) frameness resource theory to circumvent
CPT- superselection. We construct and quantify such resources for spins 0, 1/2,
and 1 and for Majorana particles, and we show that spin 0 particles only admit
classical information processing whereas particles of higher-dimensional spin
permit quantum information processing in the presence of CPT-superselection.
Our treatment of CPT inversion as indecomposable circumvents the anti-unitarity
of certain actions (C and T) by strictly considering the aggregate CPT.
