Two things struck me instantly. 

One, the quantum secure direct communication (QSDC) protocol will mean absolutely unbreakable communications for whoever uses it. Granted, quantum memory is almost unheard of outside the computer research community.  You can bet your bottom dollar, however, this will be implemented almost instantly in the US intelligence community. Once it can be miniaturized, it will be put to use in the Special Operations community.

Two, Wei Zhang, is from the University of Science and Technology of China and Nanjing University of Posts and Telecommunications, and would most likely share the findings with China, giving China, also, an almost unbreakable means of communications. 

The race is now on to remotely break QSDC protocol by the NSA and others.
