Measurement-based quantum computation (MBQC) provides a promising architecture for quantum information processing. In MBQC, computation is done through a highly entangled resource states, like a cluster state, using just single-particle measurements. We show that, even if a cluster state cannot be a unique ground state of a two-body interacting Hamiltonian, by adiabatically engineering two-body interaction, it is possible to create cluster states of logical qubits in spin-1/2 two-body interacting systems.
