1. A quantum-state readout process comprising:
illuminating with electro-magnetic radiation (EMR) plural regions of an array trap for quantum-state carriers (QSCs), the array trap defining plural array sites for containing QSCs, each of the regions including plural ones of the array sites, each region being illuminated one site at a time, each of the QSCs having first and second quantum states, each of the QSCs, when in its first quantum state, emitting EMR in response to illumination of the respective array site;
sequentially capturing emissions maps indicating for each of the regions whether or not EMR was being emitted during the time that emissions map was captured, each of the emissions maps having a respective resolution too coarse to resolve adjacent array sites of the array; and
providing a readout of the array trap based on identification of array sites containing QSCs in the first quantum state, the identification being based on the emissions maps.
