  Discrete time crystals (DTCs) are exotic many-body phases of matter in which
some observables exhibit robust subharmonic response to periodic driving. By
highlighting the connection between DTCs and a quantum error correction model,
we devise a general and realistic scheme for building DTCs exhibiting large
period observable dynamics. This is accomplished by utilizing a series of Ising
spin-1/2 chains, each of which simulates a quantum repetition code at the
hardware level, and devising a time-periodic Hamiltonian which simulates the
fault-tolerant implementation of appropriate logical quantum gates.
