For example, the T gate can't be implemented transversely in the Steane code.[2] This calls for ways of circumventing Eastin–Knill in order to perform fault tolerant quantum computation. In addition to investigating fault tolerant quantum computation, the Eastin–Knill theorem is also useful for studying quantum gravity via the AdS/CFT correspondence and in condensed matter physics via Quantum reference frame[3] or many-body theory.[4]
