Another reliable article on the Quantum Internet work.

You can’t sign up for the quantum internet just yet, but researchers have reported a major experimental milestone towards building a global quantum network — and it’s happening in space.

With a network that carries information in the quantum properties of single particles, you can create secure keys for secret messaging and potentially connect powerful quantum computers in the future. But scientists think you will need equipment in space to get global reach.

A quantum node device that might pave the way for a future space-based quantum Internet has been successfully tested for the first time aboard a small satellite.

The device, called SPEQS, has been developed by a team from the National University of Singapore (NUS) and the Glasgow-based University of Strathclyde. It contains technology for creation of the so-called correlated photons, which are a precursor for the better known entangled photons that communicate across large distances.

In an article published in the latest issue of the journal Physical Review Applied, the team led by NUS researcher Alexander Ling described first result of the experiment, which saw the SPEQS system reliably creating and measuring pairs of photons with correlated properties.

“It’s been dubbed the Google tax, but it will likely hit every global internet company operating in India—and, in turn, the country’s fledgling startup and digital advertising ecosystems.”

With the robot economy looming large in the coming decades, one solution to vanishing jobs may simply be to give people money regardless of whether or not they work.

That idea is called “basic income,” and it just gained the support of one of the tech world’s founding fathers, Internet inventor Tim Berners-Lee.

“I think a basic income is one of the ways of addressing massive global inequality,” Berners-Lee, who founded the Web in 1989, explained on a recent episode of The Economist podcast.

Make no mistake, today’s wearables are clever pieces of kit. But they can be bulky and restricted by the devices they must be tethered to. This has led engineers to create thinner and more powerful pieces of wearable technology that can be applied directly to the skin. Now, researchers at the University of Wisconsin-Madison, led by Zhenqiang “Jack” Ma, have developed “the world’s fastest stretchable, wearable integrated circuits,” that could let hospitals apply a temporary tattoo and remove the need for wires and clips.

With its snake-like shape, the new platform supports frequencies in the .3 gigahertz to 300 gigahertz range. This falls in what is set to become the 5G standard. For a mobile phone, 5G enables faster speeds and greater coverage, but with epidermal electronics, engineers have discussed the possibility that wearers could transmit their vitals to a doctor without having to leave their home.

While the idea isn’t unique, the integrated circuits created by Ma and his team have a much smaller footprint than those developed by other researchers. Earlier transmission lines can measure up to 640 micrometers (or .64 millimeters), but UW–Madison’s solution is just 25 micrometers (or .025 millimeters) thick. The Air Force Office of Scientific Research also supports Ma’s research, suggesting that his wearable breakthroughs may help pilots of the future.

Money can buy you immortality, according to the Russian internet multi-millionaire who is ploughing a fortune into a project to create a human that never dies.

The consumer marketplace is flooded with a lively assortment of smart wearable electronics that do everything from monitor vital signs, fitness or sun exposure to play music, charge other electronics or even purify the air around you — all wirelessly.

Now, a team of University of Wisconsin—Madison engineers has created the world’s fastest stretchable, wearable integrated circuits, an advance that could drive the Internet of Things and a much more connected, high-speed wireless world.

Led by Zhenqiang “Jack” Ma, the Lynn H. Matthias Professor in Engineering and Vilas Distinguished Achievement Professor in electrical and computer engineering at UW–Madison, the researchers published details of these powerful, highly efficient integrated circuits today, May 27, 2016, in the journal Advanced Functional Materials.

Anyone who has heard of Bitcoin knows that it is built on a mechanism called The Blockchain. Most of us who follow the topic are also aware that Bitcoin and the blockchain were unveiled—together—in a whitepaper by a mysterious developer, under the pseudonym Satoshi Nakamoto.

That was eight years ago. Bitcoin is still the granddaddy of all blockchain-based networks, and most of the others deal with alternate payment coins of one type or another. Since Bitcoin is king, the others are collectively referred to as ‘Altcoins’.

But the blockchain can power so much more than coins and payments. And so—as you might expect—investors are paying lots of attention to blockchain startups or blockchain integration into existing services. Not just for payments, but for everything under the sun.

Think of Bitcoin as a product and the blockchain as a clever network architecture that enables Bitcoin and a great many future products and institutions to do more things—or to do these things better, cheaper, more robust and more secure than products and institutions built upon legacy architectures.
