    "abstract": "Simultaneous measurement of multiple qubits stored in hyperfine levels of\ntrapped 111Cd+ ions is realized with an intensified charge-coupled device (CCD)\nimager. A general theory of fluorescence detection for hyperfine qubits is\npresented and applied to experimental data. The use of an imager for photon\ndetection allows for multiple qubit state measurement with detection fidelities\nof greater than 98%. Improvements in readout speed and fidelity are discussed\nin the context of scalable quantum computation architectures.",
