The Quantum internet is developing with great speed in the last couple of years. Many universities and enterprises have started their research on how to create these quantum networks and take advantage of this new technology, and some of these advancements namely the enabling Quantum technologies behind the Quantum Internet are outlined in a recent Science magazine article.
Since its public inception, the internet has sprung a worldwide technology and has evolved into what we are witnessing today, an internet revolution and digitalization that affected almost every aspect of our lives. Every little device connected to an enormous network of computers spread around the globe that are waiting and ready to share data among them at the speed of light. And now after nearly three decades, we are standing in front of another miraculous technology that can change our lives beyond this, the quantum internet.
In a push to support the wider Quantum technology industry, the US DOE (Department of Energy) has announced it is going to provide $25m towards a quantum internet which will go into research. The funds will push the development of a Quantum Internet and be used for basic research and to help design, develop and produce a quantum internet testbed at a regional scale or intra-city or inter-city level.
The internet has shown us the power of networking. Many have heard of Metcalfe’s law relating to the value of the network which grows exponentially as the number of nodes increases. It should be no surprise that some of the world’s Quantum institutes and their funders are interested in Quantum networking.
A team led by Pan Jian Wei, Chen Yu Ao, and Peng Cheng Zhi from the University of Science and Technology of China in Hefei has established the first integrated quantum communication network in the world. It is comprised of more than 700 optical fibres and two ground-to-satellite links, achieving quantum key distribution over 4,600 kilometres across the large country. This was reported in the Nature magazine.
A team of Caltech researchers and collaborators from the Jet Propulsion Laboratory (JPL) worked with Fermilab’s researchers to establish two testbeds. Using commonly available material and cutting edge quantum devices, they were able to teleport quantum information for a sustained period, sending the information to a point 44 kilometres away. The work, which is published […]
The Internet has been a true revolution our own life-time (certainly mine since I first started getting online in the mid 90’s). Now as new technologies such as Quantum are starting to gain traction, could we see a Quantum Internet, i.e. an Internet that uses Quantum Physics at the core as a protocol. We explore what the Quantum Internet actually means and how it could impact on the future of almost everyone.
As the excitement in Quantum computing and allied technologies hots up, more dedicated funding is looking at the sector. An early stave investment fund from the UK is looking to invest up to £12 million for Quantum companies based in the United Kingdom.
If you have not heard about the Quantum Internet, it might sound like science fiction, but the Quantum Internet is getting a little closer to a working reality. Scientists from around the world have steadily been increasing the distance at which typically photons can be entangled. Recently there was a similar announcement from Chinese Scientists.
We’re waiting for the first company named QOL (A variation on AOL) and for them to send us a CD (Compact Disc) through the mail! For those who are too young or weren’t even around at the time, many of us accessed the internet through a dial-up modem with tiny download speeds which are a fraction of the percentage of today’s broadband DSL speeds.
