Questions tagged [cpt-symmetry]
Use this tag for questions related to CPT symmetry, as relevant to quantum computing or quantum information theory. Charge, parity, and time reversal symmetry is a fundamental symmetry of physical laws under the simultaneous transformations of charge conjugation (C), parity transformation (P), and time reversal (T). CPT is the only combination of C, P, and T that is observed to be an exact symmetry of nature at the fundamental level (Wikipedia).
