We present a full set of tools for scalable quantum computing on mi-crostuctured linear Paul traps. We put together cold ion splitting andtransport with entangling- and single-qubit gates to achieve addressingby moving the ions in and out of the lasers. With this platform we testthe resistance of a magnetic Decoherence-Free-Subspace to ion sepa-rations of above 5mm. We?ll also present our advances in scaling upto more ions and gates between Decoherence-Free qubits. Finally we?llintroduce some new directions into quantum simulations which include2D spectroscopy and measurement of time correlation functions.
