We present a scheme for universal quantum computing using XY Heisenberg spin chains. Information is encoded into packets propagating down these chains, and they interact with each other to perform universal quantum computation. A circuit using g gate blocks on m qubits can be encoded into chains of length O(g[superscript 3+ δ]m[superscript 3 + δ]) for all δ > 0 with vanishingly small error.
