Penn researchers developed a new light-based switching method using exciton–polaritons—quasiparticles that combine photons with electrons in ultra-thin semiconductors. This approach enables ultra-low-energy, all-light signal switching, potentially overcoming key limits of electronic computing and improving the speed and efficiency of AI hardware. https://journals.aps.org/prl/abstract/10.1103/gc15-qsvf
