Physicists create hybrid light-matter particles that interact strongly enough to compute

Phys · · 421 words · By University

Researchers at the University of Pennsylvania have developed exciton-polaritons, hybrid light-matter quasiparticles, to enable all-light signal switching for computation. This technology aims to reduce energy consumption and increase speed in AI hardware by minimizing the need to convert photonic signals back into electronic ones.
