Quantum networks fused in first-of-its-kind demo that teleports entanglement instantly

Researchers at Heriot-Watt University successfully merged two independent quantum networks into a single reconfigurable system that can route and teleport quantum entanglement between eight users simultaneously. Using optical fiber costing under £100, the team harnessed chaotic light scattering to create a flexible entanglement router that supports multiple users sharing the same fiber. This breakthrough demonstration of multiplexed entanglement teleportation represents a major step toward building quantum internet infrastructure and networked quantum computers that could revolutionize medicine, materials science, and machine learning.
