The most general method of encoding quantum information is not to encode the information into a subspace of a Hilbert space, but to encode information into a subsystem of a Hilbert space. Here we present two examples of such operator error correcting subsystems, with simple spatially local Hamiltonians on square and cubic lattices. In three dimensions we provide evidence, in the form of a simple mean field theory, that our Hamiltonian gives rise to a self-correcting quantum memory.
