China’s Latest Leap Forward Isn’t Just Great—It’s Quantum

Beijing launches the world’s first quantum-communications satellite
  into orbit
State media said China sent the world’s first quantum-communications
  satellite into orbit from a launch center in Inner Mongolia about 1:40
  a.m. Tuesday. Five years in the making, the project is being closely
  watched in global scientific and security circles.
The quantum program is the latest part of China’s multibillion-dollar
  strategy over the past two decades to draw even with or surpass the
  West in hard-sciences research.

main question : Is this project credible in regard of the state of the art as known in the universities? 
Not important optional question : As for the d-wave solution, must we classify quantum computation and cryptonics as technologies which will be as such, shrouded in secrecy ?
You may answer that it is not the classical $q$-cryptography that is described in, for example, wikipedia. If so, what are the new principles?
edit : to answer to the relevant Zeldredge comment: sending a satellite is plausible, nobody doubts. But this implies to have an efficient technology, here, since at least 5 years. Following nearly all the informations on the subject, I don't see how a team got this technology 5 years ago in secret ! As today, a lot of engineers which spent a lot of time ( and money ), helped by great profs of great universities, didn't succeed to establish a valid protocol of communication ( as the theory we know states ). The alternate not polite question is , Is it not some kind of bluff ? or merely just a weak quantum application. By analogy with d-Wave which is not able to do today what we wait from a Quantum computer.
 A: I believe the best possible answer to your question is given in this Nature News article. As the article explains in detail, this type of technology has been established before, and indeed it doesn't require a special "quantum satellite":

Last year, the team showed that photons bounced back to Earth off an existing satellite maintained their quantum states and were received with low enough error rates for quantum cryptography 

What this satellite does have is an on-board source of entanglement (I believe a single-photon parametric down converter):

At the heart of their satellite is a crystal that produces pairs of entangled photons

As to how they did this, there's no secret Chinese intelligence going on here that the rest of the world wasn't aware of. They just were willing to put up the money for it. The article goes into some of the organizational details, notes that Anton Zeilinger (European) is a major part of the collaboration, and details some other efforts that have taken place around the world.
