"manipulate and identify small numbers of interacting photons with high correlation... observe difference between one photon interacting with it compared to two, since induced strong interactions between photons... more sensitive measurements with better resolution using fewer photons... one photon delayed by longer time compared to two photons...two photons become entangled in two-photon bound state... biology, advanced manufacturing and fault-tolerant quantum information processing"
