Illinois team outlines emit-then-add route to photonic graph states

Los Angeles CA (SPX) Feb 16, 2026
Physicists at the Grainger College of Engineering at the University of Illinois Urbana-Champaign have devised a new way to build large photonic graph states using currently available hardware. The scheme, described as an emit-then-add strategy, is designed to generate highly entangled states of many photons for quantum information tasks while tolerating the high loss typical of optical systems.
