    "abstract": "Motivated by the recently demonstrated ability to attach quantum dots to\npolymers at well defined locations, we propose a condensed phase analog of the\nion trap quantum computer: a scheme for quantum computation using chemically\nassembled semiconductor nanocrystals attached to a linear support. The linear\nsupport is either a molecular string (e.g., DNA) or a nanoscale rod. The phonon\nmodes of the linear support are used as a quantum information bus between the\ndots. Our scheme offers greater flexibiliy in optimizing material parameters\nthan the ion trap method but has additional complications. We discuss the\nrelevant physical parameters, provide a detailed feasibility study, and suggest\nmaterials for which quantum computation may be possible with this approach. We\nfind that Si is a potentially promising quantum dot material, already allowing\n5-10 qubits quantum computer to operate with an error threshold of 10^-3.",
