American researchers successfully conducted an experiment that for the first time demonstrates the possibility of quantum teleportation over a fiber optic cable during real internet traffic. 💡 They transmitted a quantum state of light over a distance of more than 30 kilometers through a cable that was simultaneously used for regular internet at a speed of 400 Gbps. This opens up the prospect of creating quantum networks without the need to build separate infrastructure.
How did this happen? 🤔
Quantum teleportation uses the phenomenon of quantum entanglement 🔗, where particles interact instantaneously, regardless of distance. However, the quantum signal is extremely vulnerable to electromagnetic waves and thermal collisions.
The main challenge was maintaining the integrity of quantum signals in an environment filled with 'noise' from regular data — bank transactions 💳, video streams 📹, and text messages ✉️. Scientists studied the mechanisms of light scattering and positioned photons in a spot where this scattering is minimal, allowing the protection of quantum signals from interference.
Why is this important? 🚀
Previously, similar experiments were conducted only on specially allocated cables or in simulations. The current demonstration proves that the integration of quantum communication into regular networks is possible. This:
🔐 Provides engineers with a new tool for encryption, monitoring, and computations.
⚙️ Does not require a complete overhaul of the existing infrastructure.
🌌 Brings us closer to creating hybrid networks that combine classical ultra-high-speed communications and quantum technologies.
This breakthrough changes our perception of the future of the internet and information exchange!
