Quantum teleportation takes a step toward its practical application. Deutsche Telekom and the company Qunnect have achieved a successful demonstration in Berlin, transmitting quantum states through more than 30 km of the urban fiber optic network. The key fact is that existing commercial infrastructure was used, without modifications, sharing cabling with conventional internet traffic.
Technology Ready for Deployment in Real Conditions 🔬
The experiment stands out for its execution in a real operational environment, not in a laboratory. Commercial equipment ready for industrial deployment was used, transmitting alongside classical data. The average teleportation fidelity was close to 90%, with peaks of 95%. These levels are necessary for future quantum networks that enable secure communications based on quantum cryptography and distributed computing schemes.
Your Fiber Optic Cable is Already Carrying Quantum Traffic (And You Didn't Know It) âš¡
It's likely that, while you were reading this, a quantum state was teleported through a cable under your street, alongside a cat video. The idea that the infrastructure carrying your slow internet also transports quantum physics is an unexpected twist. Soon, when calling your provider about a connection outage, you might hear: Sir, your classical data packet was lost, but your quantum entanglement has a fidelity of 95%. Does that console you?
