Chinese scientists claim space-to-ground quantum entanglement communications over distances of more than 2000 kilometers... and the chinese press claims advantage in a new "quantum space race" [Commentary: there is no independent verification of such results and... it is unnecesary and erroneous to mix a beautiful subject (quantum communications) with politics]


The concept of quantum space-to-space communications was first proposed in 2002... and it is not clear whether communications via a pair of entangled photons is the most practical or efficient avenue to exercise this class of communications


Meanwhile... tensions rise in disputed area of the South China sea


Warning against overselling quantum promises
