    "abstract": "We discuss the implementation of quantum logic in a system of strongly\ninteracting particles. The implementation is qubitless since ``logical qubits\u0027\u0027\ndon\u0027t correspond to any physical two-state subsystems. As an illustration, we\npresent the results of simulations of the quantum controlled-NOT gate and\nShor\u0027s algorithm for a chain of spin-1/2 particles with Heisenberg coupling.\nOur proposal extends the current theory of quantum information processing to\ninclude systems with permanent strong coupling between the two-state\nsubsystems.",
