Bridging AI and Human Intelligence - Multicolor Lasers and the Future of Photonic Computing
Welcome to another episode of Impact Quantum, where we explore the cutting edge of quantum computing and emerging technologies reshaping our world. Today, co-hosts Frank La Vigne and Candace Gillhoolley sit down with Vivek Raghunathan, co-founder of Xscape Photonics, to delve into the revolutionary intersection of photonics, artificial intelligence, and quantum computing. From comparing the astounding power efficiency of the human brain to today's AI clusters, to discussing how multicolor lasers could unlock massive advancements in data center performance and sustainability, Vivek shares how his company is tackling the growing power demands of AI by reimagining the future of hardware. We’ll hear why the traditional focus on faster processors is giving way to a new era where the speed and efficiency of inter-chip communication—powered by light, not electricity—becomes the key to smarter, greener computing. Tune in as we decode the transformation of data center architecture, explore the practical and philosophical implications of merging photonics and electronics, and peek into how today’s innovations lay the foundation for tomorrow’s quantum breakthroughs. Whether you’re a seasoned technologist or just quantum-curious, this is a conversation you won’t want to miss!
