In a step toward an ultra-secure global communication network, scientists have transmitted a quantum-encrypted message through the air in real-world city conditions.

The breakthrough marks the first time researchers have demonstrated that more than one bit of information per photon could be sent across this type of environment, Sportstoto in a phenomenon known as 4D encryption.

The team demonstrated 4D quantum encryption between two buildings situated nearly one-fifth of a mile apart (.3 km) - and eventually, they say it could be used to link Earth with moving objects such as an airplane, Sportstoto or even satellites in space.
