World’s first intercontinental Quantum Internet link goes live, hosts video conference

WHY THIS MATTERS IN BRIEF

Quantum communication networks are considered the platinum standard when it comes to helping create secure, unhackable networks, and now the first one is here and researchers used it to conduct the world’s first quantum internet video conference.

 

I have a saying – the future always arrives and so it is, again, today. Hackers everywhere are breaking down in tears and weeping uncontrollably onto their LAN Turtles, Raspberries and Rubber Ducks, yes, those are real hacker things… you are so not a hacker, because earlier this week scientists in China and Austria demonstrated the world’s first intercontinental Quantum Internet link by holding the world’s first ever long distance video conference. And it’s okay hackers, I promise I won’t tell anyone else about how we can send information without sending information, or create unhackable code. Shhh, those are just our secrets. Oops.

To secure the communication, a Chinese quantum communications satellite, the same one that I talked about a couple of months ago, distributed a Quantum Distribution Key (QKD), a secret string of numbers used to encrypt the video transmission so that no one could eavesdrop on the conversation. In the call, chemist Chunli Bai, president of the Chinese Academy of Sciences in Beijing, spoke with quantum physicist Anton Zeilinger, president of the Austrian Academy of Sciences in Vienna.

“It’s a huge achievement,” says quantum physicist Thomas Jennewein of the University of Waterloo in Canada, who was not involved with the project, “it’s a major step to show that this approach could be viable.”

Using a technique known as QKD, scientists share secret strings of numbers while ensuring that no eavesdroppers can intercept the code undetected. Those quantum keys are then used to encrypt information sent via traditional internet connections. Decoding the transmission requires the same key used for encryption, foiling would-be snoops.

China’s Micius satellite, which launched in 2016, uses lasers to beam photons, or light particles, to ground stations on Earth and in this case Micius sent a series of photons encoding a string of 0s and 1s to a ground station near Beijing. The satellite then stored information about the sequence until it reached a station near Vienna, where Micius beamed down another string of photons. Then the satellite combined the two sets of numbers and relayed additional information to the stations to allow them to create matching keys.

Previously, scientists have used Micius to distribute quantum keys between the satellite and the ground, and teleport photons from the ground into space, despite being separated by 1,200 kilometers, but the video chat marks the first time researchers were able to exchange quantum keys between two different continents.

Although the chat was not completely secure from hacking, it was about a million times as secure as what’s possible with standard, or classical types of encryption, says Rupert Ursin, a physicist at the Institute for Quantum Optics and Quantum Information in Vienna and a member of the Austrian team. The Chinese and Austrian teams also exchanged images using theoretically uncrackable methods.

In the future, scientists envision widespread quantum networks allowing secure communication worldwide.

“We are facing, now, a new era of having a global quantum internet ready to be deployed,” Ursin says, and that’s a staggering achievement.

However, for all those cybersecurity folks I lulled into a false sense of security when I said quantum networks are unhackable, well, that might not strictly be true because in February this year a bunch of Canadian researchers managed to hack one, but, it has to be said I’m sceptical so I’m keeping an eye on it for you. Check back later.

Quantum ! Here goes my Fav. Word – like in the: Q – computers ? Q physics ? Q Olympic next ?! Lol June ( who else)

@Matthew Griffin #unhackable! is a pretty big statement to back, in my experience and research its hackable and with current infrastructure it has quite enough weak points to not completely rely on it.

I know some scientists may find the following comment “amateurish”. yet here I go.

Q-Networks and QKD are incredibly exciting technologies for securing data! I often tell my friends that once we achieve QSupremecy, most non Q-Based Security technologies (including Blockchain) could be rendered useless. However, not a single technology, including Q-Networks or QKD, represent a digital security panacea. Without even debating the possibility of Quantum Networks and QKD having vulnerabilities, let me just say that ANY Data Security technology is but part of a full security solution.

All scientists know that EVERY chain (of any type) is no stronger than it’s weakest link. As I ponder the number of weak links that exist in EVERY security solution, I decided to just start naming some of them off the top of mind and see if any are concerning: First, there is Alice, and then there is Bob. And, well, I’ll just stop with these 2 for now, since according to IBM, they caused over 60% of all known breaches in 2016.

I know how obvious this is to all my security experts. But too many companies and agencies are TOO comfortable with their current security solutions and plans.

@Farhan I agree – everyone is telling us these networks are unhackable but as you’ll see in the article I mentioned the canadian team who say they managed to hack one – personally I think they’ll be difficult to hack but like you say not impossible

@John D. Well said John and I didn’t think it was amateurish 😉

[…] Barzanjeh at the Institute of Science and Technology in Austria, who also demonstrated the world’s first unhackable quantum internet video call, have announced they’ve used entangled microwaves to create the world’s first quantum radar. […]
