Photonic computing uses light instead of electrons to store information and to perform computations, offering the promise of faster analog computer processing with lower energy overhead. Now two companies have demonstrated photonic processers that take a step toward this reality. One device, built by researchers at Lightintelligence, a photonics computing company in Singapore, solves hard optimization problems faster than traditional processors [1]. The other, developed by Lightmatter, a photonics computing company in California, runs modern artificial intelligence (AI) models with high accuracy and high energy efficiency [2].
