China Makes Techonological Breakthrough With Quantum Space Satellite

China’s Quantum Satellite — it’s now official China has beaten the US with their launch of a Quantum Satellite for secured communications. At this rate; US can possibly expect China has and will continue to advance its networking infrastructure. US Government has a good strategy in place.

Quantum space satellite, a satellite under the Chinese space program, is making waves in the country as it is the first satellite to deliver quantum communication in China, according to Chinese state media.

This new innovation is a breakthrough technology and it will be an asset for China’s power all over the globe.

Poll On Attitudes Towards Robots Finds Canadians As Pessimistic As It Gets

Given robotics history, I can understand Canada’s viewpoint. However, as technologies such as Quantum is applied to AI; we then will see real improvements in robotics. Until Quantum is AI’s platform; we will see robotics still fall short in many areas and will continue to see limited use and adoption.

Nowhere is the world’s robotic future more controversial than in Canada.

In a new global poll from travel site Travelzoo, Canadians were the least likely to agree that robots will make people’s lives better.

A majority of Canadians — 63 per cent — say robots will improve their lives, but that’s still a lower percentage than in other surveyed countries. Seventy-one per cent of Americans and 97 per cent of Chinese respondents expect robots to make things better.

Windows Could Soon Power the Entire Building

Q-Dots windows to power homes and other buildings.

Researchers at the Los Alamos National Lab may have found a way to take quantum dots and put them in your ordinary windows to turn them into solar collectors.

Photovoltaic cells may be cheaper and more efficient than ever, but you still need to find a place to put them.

Looking to solve these space constraints, Los Alamos partnered with the University of Milano in Italy to see if they could turn windows into electric generators.

As nanocrystals roughly one-billionth of a meter across, — that is as small as 10 atoms wide — quantum dots can absorb light at one wavelength, convert it and re-emit it at another wavelength.

So the dots would absorb sunlight and convert it to a wavelength best suited for the photovoltaic cells, then be guided to the solar cells installed at its edges to electricity.

The University of Milan is responsible for the new industrial method that embeds the dots in a transparent material.

Gates thinks quantum computing in the cloud may come in a decade

I don’t believe that we’re a decade away given the advancements around Quantum infrastructure work such the Quantum Internet and Platform. Too much progress is showing me within the next 7 to 8 years is a possibility especially with the race that we’re all in.

Bill Gates did an Ask Me Anything on Reddit Tuesday and said that there’s a chance within six to ten years that “cloud computing will offer super-computation by using quantum.”

“It could help users solve some very important science problems, including materials and catalyst design,” Gates wrote.

Quantum computing could help users analyze very large amounts of data quicker than they can do now with processor-based computers. While D-Wave offers quantum computing hardware, there is some debate over whether the products actually achieve quantum computing. Gates noted that Microsoft and others are working on quantum computing but steered clear of any debate about whether actual systems are on the market now.

MIT’s new 5-atom quantum computer could make today’s encryption obsolete

Much of the encryption world today depends on the challenge of factoring large numbers, but scientists now say they’ve created the first five-atom quantum computer with the potential to crack the security of traditional encryption schemes.

In traditional computing, numbers are represented by either 0s or 1s, but quantum computing relies on atomic-scale units, or “qubits,” that can be simultaneously 0 and 1 — a state known as a superposition that’s far more efficient. It typically takes about 12 qubits to factor the number 15, but researchers at MIT and the University of Innsbruck in Austria have found a way to pare that down to five qubits, each represented by a single atom, they said this week.

Using laser pulses to keep the quantum system stable by holding the atoms in an ion trap, the new system promises scalability as well, as more atoms and lasers can be added to build a bigger and faster quantum computer able to factor much larger numbers. That, in turn, presents new risks for factorization-based methods such as RSA, used for protecting credit cards, state secrets and other confidential data.
