Researchers have increased the speed of quantum key distribution from hundreds of kilobits to megabits per second:
Researchers have packed extra information onto single photons to speed up quantum key distribution (QKD) systems. QKD uses a characteristic of quantum mechanics to protect keys used to encrypt data using classical crypto schemes: if Eve tries to snoop on the key Alice is sending Bob, the quantum state/s a photon carries are destroyed. Alice and Bob know there's an eavesdropper, and the key Eve eavesdropped is useless.
However, compared to conventional telecommunications systems, QKD is slow: most systems based on photon-by-photon transmission of crypto keys run at speeds of hundreds of kilobits per second.
Research from Duke University's Nurul Taimur Islam, with collaborators from Ohio State University, Oak Ridge National Laboratory, and the National University of Singapore, achieved megabit key distribution rates using off-the-shelf components, meaning existing photonic QKD systems could be adapted to use it their work. In a paper based on research funded by the United States Navy and Defense Advanced Research Projects Agency (DARPA), published in Science Advances [open, DOI: 10.1126/sciadv.1701491] [DX] and available as pre-press at arXiv, the researchers explained that to get faster key distribution rates, they worked to overcome the limits on photon detectors' speed.

Letting aside MH 370 was a Malaysian flight, not a Chinese one, what exactly "disappeared outside of a... flight" does mean?
They were somehow extracted while in flight or what? They were flying outside MH370 and were disappeared while doing so?
Inquiring minds want to know.

They used the same method the Jews used to hijack the Global Hawks...er...the 747's...and fly them into the twin towers (a Global Hawk was flown into the Pentagon.)
Remote control redirecting. Those 14 or so quantum experts from Freescale were far too valuable to fly back into American hands. They were disappeared off radar and redirected into the mainland...or somewhere else.

Except that the 20 freescale semi people disappeared were 12 Malaysians and 8 Chinese [theregister.co.uk], heading towards Beijing.
It would have made a lot more sense for the Chinese to let the flight land and disappear them inside the airport or the cars carrying them from there.
It you really like this line of consptheory, is more plausible that the CIA learnt about the impeding defection and blew up the plane rather than let them get out of the American hands.

Clearly your drinking is destroying what little ability you have to reason, eth.
The real story here is:
The libruls are allowing a raghead terr'ist to work on this stuff. I hope our beloved president throws this jihadist and every other piece of shit like him that hates 'murikkka *under* the jail forever!
Those mohammed's dick sucking scum need to be disemboweled alive and dumped into our amber waves of grain so their blood can be fertilizer for our great nation as they bleed out.
But, no! Those soft-headed libruls like Chuck, Nancy and John McCain want to give the terr'ists quantum encryption because they hate our way of life and want Sharia law throughout the world.
Thankfully, our most popular president ever, with the help of *real* 'murikkans like Richard Spencer, the wonderful Steve Bannon, Dillon Hopper and other right-thinking real (read: white) humans, will kill and dismember as many muzzie terr'ists and other darkies until they're no longer a threat to our way of life.
