Si kastaba ha noqotee, Donald Knuth wuxuu ku doodayaa in dib loo soo celin doono horumarka mustaqbalka si looga faa'iideysto hufnaanta iyo hufnaanta caqliga saddex-geesoodka ah. Hal dariiqo oo ay taasi ku dhici karto waa iyada oo la isku darayo kombuyuutar indhaha leh oo leh nidaamka caqliga saddex-geesoodka ah. Kombuyuutar saddex-geesood ah oo adeegsanaya fiber optics wuxuu isticmaali karaa madow sida 0 iyo laba isbeddel oo orthogonal ah oo iftiin ah sida 1 iyo -1. IBM sidoo kale waxay si dhif ah uga warbixisaa mowduucyada xisaabinta saddex-geesoodka ah (warqadeeda), laakiin si firfircoon ugama hawl gasho. Isgoyska Josephson waxaa loo soo jeediyay inuu yahay unug xasuusta saddex-geesoodka ah oo isku dheelitiran, iyadoo la adeegsanayo socodka superconducting, ama dhinaca saacadda, ama dhinaca saacadda.
