“This technology could revolutionize the field of telecommunications,” says Krishnaswamy, director of the Columbia High-Speed and Mm-wave IC (CoSMIC) Lab. “Our circulator is the first to be put on a silicon chip, and we get literally orders of magnitude better performance than prior work. Full-duplex communications, where the transmitter and the receiver operate at the same time and at the same frequency, has become a critical research area and now we’ve shown that WiFi capacity can be doubled on a nanoscale silicon chip with a single antenna. This has enormous implications for devices like smartphones and tablets.”

Krishnaswamy’s group has been working on silicon radio chips for full duplex communications for several years and became particularly interested in the role of the circulator, a component that enables full-duplex communications where the transmitter and the receiver share the same antenna. In order to do this, the circulator has to “break” Lorentz Reciprocity, a fundamental physical characteristic of most electronic structures that requires electromagnetic waves travel in the same manner in forward and reverse directions.

“Reciprocal circuits and systems are quite restrictive because you can’t control the signal freely,” says PhD student Negar Reiskarimian, who developed the circulator and is lead author of the Nature Communications paper. “We wanted to create a simple and efficient way, using conventional materials, to break Lorentz Reciprocity and build a low-cost nanoscale circulator that would fit on a chip. This could open up the door to all kinds of exciting new applications.”

A microchip that filters out unwanted radiation with the help of graphene has been developed by scientists from the EPFL and tested by researchers of the University of Geneva (UNIGE). The invention could be used in future devices to transmit wireless data ten times faster.

EPFL and UNIGE scientists have developed a microchip using graphene that could help wireless telecommunications share data at a rate that is ten times faster than currently possible. The results are published today in Nature Communications.

“Our graphene based microchip is an essential building block for faster wireless telecommunications in frequency bands that current mobile devices cannot access,” says EPFL scientist Michele Tamagnone.

Creative approach and I like it. I advise IT leaders, developers, architects, etc. to start learning as much as they can about Quantum Technology because technology in the next 6 to 7 years will begin the accelerated adoption of this technology and at that point it will be too late for folks in tech to catch up. Now is the time to learn and keep track of the progression of this technology as well as understand where and how this technology can be leveraged earlier in various areas of the infrastructure, devices, and even in industry.

Researchers gave internet users games that simulate quantum physics experiments, and internet users gave the researchers more elegant solutions.

The question is what does Stefano Pirandola and Samuel L. Braunstein consider “hybrid” when it comes to QC? In much of the Quantum research today only shows us things like “synthetic diamonds”, etc. are added to stablize data storage and transmissions not much else.

Physics: Unite to build a quantum Internet. Braunstein.

For communications; teleporting is definitely key. When it comes to Quantum Internet, one only needs to consult with researchers at Los Alamos National Lab to see how they have evolved in this space since 2009.

Advances in quantum communication will come from investment in hybrid technologies, explain Stefano Pirandola and Samuel L. Braunstein.

Many folks talk about the whole AI revolution; and indeed it does change some things and opens the door the for opportunities. However, has it truly changed the under lying technology? No; AI is still reliant on existing digital technology. The real tech revolution will come in the form of Quantum tech over the next 7 to 8 years; and it will change everything in our lives and industry. Quantum will change everything that we know about technology including devices, medical technologies, communications including the net, security, e-currency, etc. https://lnkd.in/bJnS37r

If you were born in the 1970s or 1980s, you probably remember the Jetsons family. The Jetsons are to the future what the Flintstones are to the past. That futuristic lifestyle vision goes back several decades; self-driving vehicles, robotic home helpers and so on. What looked like a cartoon series built on prolific imagination seems somewhat more real today. Newly developed technologies are becoming available and connecting everything to the internet. This is the-internet-of-things era.

These ‘things’ are not new. They are just standard devices – lights, garage doors, kitchen appliances, household appliances – equipped with a little intelligence. Intelligence that is possible thanks to three emerging technologies: sensors to collect information from surroundings; the ability to control something; and communication capability allowing devices to talk to each other.

WebTorrent is best described as a BitTorrent client for the web. It allows people to share files directly from their browser, without having to configure or install any additional software. Now WebTorrent Desktop has arrived, offering a lightweight yet feature-rich streaming and castable experience on Windows, Linux and Mac.

Every day millions of Internet users fire up a desktop-based BitTorrent client to download and share everything from movies, TV shows and music, to the latest Linux distros.

Sharing of multimedia content is mostly achieved by use of a desktop client such as uTorrent, Vuze, qBitTorrent or Transmission, but thanks to Stanford University graduate Feross Aboukhadijeh, there is another way.

As our cars become increasingly connected to the internet, and eventually drive themselves, we’re going to want them to be rock-solid secure. The recent Chrysler exploit and FBI warning both highlighted just how vulnerable our vehicles can be to malicious hackers.

The idea of anti-virus software for cars has been around for several years, and this year there’s even an entire conference about in-car cybersecurity. Karamba Security is a new company in the space that is offering what amounts to a firewall for your ride.

Don’t miss our biggest TNW Conference yet! Join us May 26 & 27 in Amsterdam.

Samsung is exploring the development of a contact lens that can project images directly into the users’ eye, take photographs and connect wirelessly to a smartphone, a patent application has revealed.

The South Korean copyright authority has published a 29-page application made by the consumer electronics firm two years ago, reported the technology blog Sammobile, offering a rare insight into a science fiction vision of a future technology that could be closer than we think.

The lens could overlay internet-connected services directly into the user’s line of sight, in an example of what is known as augmented reality. It could also discreetly – even covertly – take photographs. The device would be controlled by eye movements or blinking, according to the patent, and it would connect with a smartphone.
