Quantum computers need a network. In this episode of The Quantum Computing Podcast, Lucas and Luna explore the emerging field of quantum internet — a dedicated network that distributes entanglement between distant quantum processors. They break down the fundamental challenge: transmitting fragile quantum states over fiber optics without destroying them. Lucas explains the concept of quantum repeaters, devices that use entanglement swapping to extend range, and cites the recent proof-of-principle demonstration by a European consortium that achieved entanglement distribution over 50 kilometers of deployed fiber. Luna asks how this compares to classical internet infrastructure and whether existing fiber can be reused. They discuss the timeline: functional regional quantum networks within five years, global quantum internet perhaps a decade away. The episode closes with a forward-looking question about who will build and own this next-generation network.
