La teletransportación cuántica convivió con tráfico convencional en fibra óptica, y otro ensayo llevó el entrelazamiento a una red urbana real.

Researchers at the University of Science and Technology of China have successfully entangled two quantum memories across 420 kilometers of optical fiber, surpassing previous records by over four times. This achievement, published in *Physical Review Letters*, represents a significant step toward realizing a quantum internet. Optical fibers currently form the backbone of global communication systems, but this study explores enhancing their functionality through entangled quantum particles. Such technology could enable secure data transmission and unprecedented computational power. The experiment involved maintaining quantum coherence over vast distances, overcoming challenges like photon loss in fiber networks. While quantum entanglement does not permit faster-than-light communication, it allows for instantaneous correlation of states, which is critical for quantum computing advancements. Critics note that the process requires statistical analysis across many photons to confirm entanglement, emphasizing the complexity of scaling such systems. This breakthrough underscores the potential of quantum technologies to revolutionize fields like cryptography and distributed computing.

Het is de onderzoekers gelukt om een snelle, onkraakbare en stabiele verbinding te maken op de experimenteertafel, de basis voor een toekomstig quantuminternet.
