I agree with the others that Chinese academics tend to be unreliable to put it nicely, and Spain's claim is much better. As to how it works for communications, if you remember your chemistry, this works equally well for electrons as photons. Take two hydrogen atoms, and if you entangle their electrons, one electron will have a quantum state of: n=1, l=0, m=0, and s= +1/2 and the other electron has the quantum state of: n=1, l=0, m=0, and s= -1/2. Once they are entangled, if you change the s-state on the first electron to s= -1/2 the s-state on the second one will immediately change to s= +1/2 regardless of its location, and if you change the s-state on the second electron the s-state of the first electron immediately flips. The trick to communications is you need something that can read the s-state and change it on both ends. Then you code one end to read +1/2 as 1 and -1/2 as 0 and the other end the opposite way, you can send and receive any digital information almost instantaneously, regardless of the distance.
