Abstract
A device includes a plurality of photon sources coupled to a plurality of output terminals. The plurality of photon sources are coupled together, by a first switch layer, into a plurality of photon source groups. The first switch layer comprises a plurality of switches. The device further includes a second switch layer coupled to output terminals of the first switch layer. The second switch layer includes a plurality of second layer n-by-n switches and a plurality of second layer l-by-l switches, wherein l is less than n. At least two output terminals from two respective photon sources residing within a first photon source group of the plurality of photon source groups and a second photon source group of the plurality of photon source groups are coupled directly to respective output terminals of the device without being coupled to any intervening second switch from the second switch layer.
