Durban's Moses Mabhida Stadium in South Africa is employing quantum cryptography to protect data networks at the World Cup. With the quantum system, videos, e-mails and phone calls from the stadium and a nearby operations center for police, firefighters and military personnel is theoretically impenetrable.
Quantum cryptography involves encoding information in photons, and enables two parties to produce a shared random bit string known only to them. When a third party attempts to hack the key, anomalies are easily detected.
After the World Cup, Durban plans to deploy more quantum security system throughout the city.
