SHANGHAI, China (PNN) - August 28, 2017 - Chinese scientists have successfully sent information between entangled particles through sea water, the first time this type of quantum communication has been achieved underwater.
In this proof-of-concept experiment, information was sent across a 3.3-meter (10.8-foot) long tank of seawater, but the researchers predict they should be able to use the same technique to send unhackable communications close to 900 meters (0.55 miles) through open water.
