    "abstract": "We provide a broad outline of the requirements that should be met by\ncomponents produced for a Quantum Information Technology (QIT) industry, and we\nidentify electromagnetically induced transparency (EIT) as potentially key\nenabling science toward the goal of providing widely available few-qubit\nquantum information processing within the next decade. As a concrete example,\nwe build on earlier work and discuss the implementation of a two-photon\ncontrolled phase gate and a one-photon phase gate using the approximate Kerr\nnonlinearity provided by EIT. We rigorously the dependence of the performance\nof these gates on atomic dephasing and field detuning and intensity, and we\ncalculate the optimum parameters needed to apply a pi phase shift in a gate of\na given fidelity. Although high-fidelity gate operation will be difficult to\nachieve with realistic system dephasing rates, the moderate fidelities that we\nbelieve will be needed for few-qubit QIT seem much more obtainable.",
