http://embedded-computing.com/news/rising-quantum-dots-market/#

Quantum Dots Market is driven by increasing demand for energy efficient displays and lighting solutions, North America accounted for largest quantum dots market share, use of quantum dots in solar cells and VLSI design is expected to open new possibilities for quantum dots market.

Quantum dots are semiconducting nanoparticles that range from 1nm to 10nm diameter in size and demonstrate quantum mechanical properties. The peculiarity of quantum dots is that they have ability to unite their semiconductor properties with those of nanomaterials. In addition, tunable nanocrystal size and superior optical properties have made quantum dots attractive semiconducting material for variety of applications in the field of healthcare, optoelectronics, solar energy, and security among others.

Will quantum computing be BlackBerry’s Waterloo?

Definitely could see QC being Blackberry’s achilles heal.

WATERLOO — Advances in quantum computing could present a huge challenge to BlackBerry’s biggest competitive advantage — its vaunted security software that has never been hacked.

This seldom talked-about subject was raised recently by John Thompson, the associate vice-president for research at the University of Waterloo. Thompson was listening to a presentation by Mike Wilson, a senior vice-president and chief evangelist for BlackBerry, at a medical technology conference in Kitchener about a month ago.

Both quantum computing and BlackBerry have deep roots in Waterloo. BlackBerry pioneered the smartphone industry and the wireless Internet from its suburban office parks in Waterloo.

End of nations: Is there an alternative to countries?

Nation states cause some of our biggest problems, from civil war to climate inaction. Science suggests there are better ways to run a planet.

By Debora MacKenzie

Try, for a moment, to envisage a world without countries. Imagine a map not divided into neat, coloured patches, each with clear borders, governments, laws. Try to describe anything our society does – trade, travel, science, sport, maintaining peace and security – without mentioning countries. Try to describe yourself: you have a right to at least one nationality, and the right to change it, but not the right to have none.

The future of storage may be in DNA

Definitely been seeing great research and success in Biocomputing; why I have been looking more and more in this area of the industry. Bio/ medical technology is our ultimate future state for singularity. It is the key that will help improve the enhancements we need to defeat cancer, aging, intelligence enhance, etc. as we have already seen the early hints already of what it can do for people, machines and data, the environment and resources. However, a word of caution, DNA ownership and security. We will need proper governance and oversight in this space.

Humanity uses a staggering amount of storage, and our needs are only expanding as we build data centers, better cameras, and all sorts of other data-heavy gizmos. It’s a problem scientists from companies like IBM, Intel, and Microsoft are trying to solve, and the solution might be in our DNA.

A recent Spectrum article takes a look at the quest to unlock the storage potential of human DNA. DNA molecules are the building blocks of life, piecing our genetic information into living forms. The theory is that we can convert digital files into biological material by translating it from binary code into genetic code. That’s right: the future of storage could be test tubes.

In April, representatives from IBM, Intel, Microsoft, and Twist Bioscience met with computer scientists and geneticists for a closed door session to discuss the issue. The event was cosponsored by the U.S. Intelligence Advanced Research Projects Activity (IARPA), who reportedly may be interested in helping fund a “DNA hard drive.”

Google’s Sundar Pichai has been hacked — which CEO will be next?

Geez! Is no one safe anymore; Google’s CEO has been hacked. Oh boy; guess there is definitely a bigger message to Google and others of big tech around this one. Whose next Bezos, Schmidt, etc? BTW — how is that AI working out.

Google CEO Sundar Pichai has become the latest tech executive to have a social media account hacked, and the group responsible says more targets will follow.

On Sunday, a group of hackers calling themselves OurMine briefly took over Pichai’s account on Quora, a question-and-answer site.

“We are just testing your security,” the hackers wrote, with the same message auto-posted via Quora to Pichai’s Twitter account. On Monday, the posts had been deleted.

New, better way to build circuits for world’s first useful quantum computers

We’re on a roll with QC.

The era of quantum computers is one step closer as a result of research published in the current issue of the journal Science. The research team has devised and demonstrated a new way to pack a lot more quantum computing power into a much smaller space and with much greater control than ever before. The research advance, using a 3-dimensional array of atoms in quantum states called quantum bits—or qubits—was made by David S. Weiss, professor of physics at Penn State University, and three students on his lab team. He said “Our result is one of the many important developments that still are needed on the way to achieving quantum computers that will be useful for doing computations that are impossible to do today, with applications in cryptography for electronic data security and other computing-intensive fields.”

The new technique uses both laser light and microwaves to precisely control the switching of selected individual qubits from one quantum state to another without altering the states of the other atoms in the cubic array. The new technique demonstrates the potential use of atoms as the building blocks of circuits in future quantum computers.

The scientists invented an innovative way to arrange and precisely control the qubits, which are necessary for doing calculations in a quantum computer. “Our paper demonstrates that this novel approach is a precise, accurate, and efficient way to control large ensembles of qubits for quantum computing,” Weiss said.

Virginia looks at new opportunities for Wallops spaceport

WALLOPS ISLAND — With space station resupply launches expected to resume in August and a runway under construction for testing drone flights, Virginia is looking at another opportunity to lure a major federal research program to the state’s expanding spaceport complex on this Eastern Shore barrier island.

The U.S. Department of Homeland Security is expected to begin looking for a place to base a new “science and technology testing ground” for unmanned vehicle systems — operating in the air and underwater — and boosters say the regional spaceport would be an ideal fit.

“What better place to do it than here?” said Peter Bale, chairman of the Wallops Island Regional Alliance, as members of the House Appropriations Committee visited last week.

Science Council to make clear position on lifting military-linked research ban

Interesting.

The Science Council of Japan will make clear its position on military-linked research — possibly overturning a decades-long ban — by early next year, the academic group said Friday.

A committee of 15 academics from fields ranging from physics, political science to law held its first meeting to discuss whether to revise statements released by the council in 1950 and 1967 stating that the group will “never engage in military research.”

Over the next several months, the committee will hold five or six sessions to discuss how they should assess changes in the security and technology environment, how to define dual-use research, how studies tied to national security would impact academic transparency and how inflows of defense-related funding would alter the overall nature of research.

Optical antenna scatters different colors of light in different directions

They’re calling this a 3 Axis Vector Nano Superconducting Quantum Interference Device which is pretty exciting because it enables the ability to make smaller and cheaper devices for measuring light, such as optical sensors and photodetectors which are and will grow in demand especially with some of the AI technology that is and will be developed. Optical sensors are used to read the gestures/ expressions of a face which are important in security, AI technology, etc. Just hope the cost savings is passed on.

(Phys.org)—Researchers have fabricated a silicon optical antenna that is somewhat like an extremely small, special kind of prism. This is because when a red light shines on the optical antenna, the light turns right, but when the light is another color such as orange, it turns left.

This unusual property, which is called “bidirectional color scattering,” enables the optical antenna to function effectively as a passive wavelength router for visible . The device could have applications for innovative light sensors, light-matter manipulation, and optical communication.

The new optical antenna was developed by a team of researchers, Jiaqi Li et al., at imec (Interuniversity MicroElectronics Center) and the University of Leuven (KU Leuven), both in Leuven, Belgium. Their work is published in a recent issue of Nano Letters.
