Abstract: A system is provided for imaging trapped ions in a quantum computer. The system includes an ion trap that traps qubit ions and includes electrodes that shuttle individual qubit ions between a first position and a second position spatially different from the first position. The system includes a first imaging lens that collects fluorescence from a qubit ion that is trapped over a surface of the ion trap; a first sensor in a first optical path output from the first imaging lens; a first pick-off mirror in a second optical path output from the first imaging lens that is different than the first optical path; a second imaging lens that collects fluorescence that is reflected from the first pick-off mirror; and a second sensor in a third optical path. Moreover, a controller controls the electrodes to shuttle the qubit ion from the first position to the second position.
