1. A quantum-state readout process comprising:
illuminating with illumination electro-magnetic radiation (EMR) plural regions of a quantum-state carrier (QSC) array of QSCs, the QSC array defining plural QSC sites for containing QSCs, each of the regions including plural ones of the QSC sites, each region being illuminated one QSC 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 emissions EMR in response to the illumination of the respective QSC site;
sequentially capturing emissions maps of the QSC array, each emissions map consisting of an array of pixels;
grouping pixels of at least one emissions map into multi-pixel superpixels such that each superpixel has within its field of view an optimal alignment position for each QSC site most recently illuminated at the time the emissions map was captured, each multi-pixel superpixel being larger than a respective QSC site of the QSC array and no larger than the region to which the respective QSC site resides, at least one superpixel having areas of at least two regions in its field of view while the respective QSC is illuminated;
for each QSC site of the QSC array, making determinations whether or not the QSC site contained a QSC in its first quantum state at the time the QSC was illuminated based on pixel values of pixels in respective superpixels; and
generating a quantum-state readout based on the determinations.
