Industrial scale qubit chip

21 May

The quantum chip (qbit or quBit) can now go on an industrial scale, a team of researchers from Denmark and the US announced last month that the technology is ready.
The problem was to scale up in such a way that computers could use chips, so far the qubits’ quantum computing was not robust enough to operate in noisy environments on a full computer.
Another problem was scale production, out of specialized laboratory and produced in conventional factories, they had to work with the semiconductors and normal circuit boards, with a combination of the semiconductors of conventional chips with aluminum and aluminum arsenide, the part industrial revolution is solved.
The team is led by Professor Antonio Fornieri, who has built a quantum memory chip and promises that quantum computers can now be produced in scale. the most resilient qubits by a combination of a semiconductor, the Indian arsenide, with a superconductor, aluminum, in a planar device, called the so-called Josephson junction, capable of treating Majorana quasi-particles.
Majorana quasiparticles are zero-mode fermions, which emerge on the surface of topological superconductors, which function as fault-tolerant and noise-free qubits.
The teacher Fornieri said: “Our prototype is a significant first step in using this kind of system to make quantum bits that are protected against disturbances.” “We still need some adjustments at the moment – we can improve design and materials, but it’s a potentially perfect structure.”.
The article was published in Nature and is authored by Fornieri and his team: Antonio Fornieri, Alexander M. Whiticar, F. Setiawan, Elias Portolés, Asbjørn CC Drachmann, Anna Keselman, Sergei Gronin, Candice Thomas, Tian Wang, Ray Kallaher, Geoffrey C. Gardner, Erez Berg, Michael J. Manfra, Ady Stern, Charles M. Marcus, Fabrizio Nichele, Evidence of Topological Superconductivity in Planar Josephson Junctions. Nature Vol .: 569, pages 89-92.

The informational impact

08 May

Society, information abundance, information turnaround and other appeals to the novelty that arose not with the internet, but with the computer and the possibility of handling the data in volume (Big Data) certainly brought a new perspective.

Anyone who wanted to understand eighteenth-century society should study the industrial revolution and its impact on manpower and the production of serial products, today anyone who wants to analyze contemporary society cannot lose sight of the volume of data they are produced to try to make this volume accessible to society.

But it is not so, because together with this volume came by previous process, it is only to check with history, not the romantic dreamed by idealists, but the real one and to realize that the problem of both Information in volume and depth, made it difficult to digging and knowing what is essential.

We have already posted here Karl Kraus, who complained to journalists in the midst of the threat of a second world war because of misunderstood news highlighting only interests. In an interview with the newspaper El Pais, Peter Sloterdijk also warned that “it is difficult to think of contemporary society,” Byung Chul Han his disciple alert to “active vita” (Chul-Han)

The phenomenon we witnessed in which information became practically a commodity, started with the digital model of Shannon (photo) and the Turing machine in the 1930s, and accelerated with the construction of modern computers.

What we witnessed and did not always participate in an “active” and reflexive way, able to elaborate thinking about information, is the fragmentation of knowledge accelerated by new gadgets, but which was initiated by a crisis in the thinking of Western society, which only deepened over the years, its initializing in modernity.

The Movie The game of imitation (2015) illustrates the life of Alain Turing and his theory:

 

 

 

Alexa: between complaints and new kit

15 Apr

In the midst of allegations of invasion of user privacy, use of data to augment Amazon’s personal assistant: Alexa, the company launches a kit that can further enhance the development of its “intellectual” ability the Alexa Skills kit ( ASK).
The claims made by Bloomberg were that employees would be listening to conversations and using private information, the company defended itself by saying that “an extremely small sample” was used and that its employees did not have access to identification.
The goal would be to help users “better understand their requests and ensure the service works well for everyone,” the machine learning and deep lerning functions are used.
The company of Jeff Bezos began to carry out tests in Portuguese, and already released the kit to reach the market of the 3rd. the most widely spoken language on the Internet, developers will be able to develop the “skills” of the voice assistant and thus expand the ecosystem of the product in Portuguese.
The idea is to anticipate the hardware products that will be released to Alexa, incorporating the Internet of Things (IoT) and when they were released already have developments.
The Amazon testflight, as it is known, has versions for Apple and iOS, but free software developers non Vasile, there are development alternatives.
In addition to releasing the kit, Amazon also stated on its website that enterprises: Bose, LG and Intelbras are development products.
This is basic introduction to ASK:

 

The Web turned 30

13 Mar

Still confuse the Internet, the Web and the Network, although they may be superimposed, they are different aspects that united the world, the pessimists say worse, the optimists say it points to the future, the realists say it is a new time with difficulties and facilities, well used will be promising for the future.
On March 9, at CERN where Tim-Berners Lee worked when he made a proposal for an Internet interpreter called and used the term web (not net), the idea of his original article was an ease of handling scientific texts online that at the very moment they were written were ready to be read, which bloggers and tweeters do today, but that was Web 2.0 in 2005.
In Geneva at CERN Berners-Lee met with Robert Cailliau, a computer science engineer who was not mentioned at all, but it was in fact that he made the first hypertext system, they were joined by other experts to discuss the present and future of the World Wide Web, or Web. 
The event, called Web @ 30, was opened yesterday (12/03) by CERN General Manager Fabiola Gianotti, in collaboration with two organizations founded by Berners-Lee: the World Wide Web Foundation and the World Wide Web Consortium ( W3C), CERN has recently restored the first website and online brower, shown at the Hackathon event (February 11-15, 2019). 
Security issues, free internet maintenance policies, governments and business structures want their control and in some countries it is not a free service, fake news and others were topics for discussion. 
A promising theme for the future is the SOLID project, we have already posted a post on it, it is in full development with the collaboration of MIT researchers, but the expectation is high and there will still be a lot of expert work to give the world a reliable Web.
Suhayl Khan showed how to access the browser in online mode using technology from the 1960s (when there was only internet and with few facilities) (Video: Suhayl Khan):

 

Foldable smartphone, novelty?

12 Mar

The Mobile World Congress fair held last week in February in Barcelona brought the folding screens as a novelty, foldable in half only, and whose novelty is to improve the user experience, both joining the two halves, as separating the application and the set of them in two screens, creating a new, now active “window” experiencie, now in two screens.
The Huawei Mate X comes and soon Samsung will launch the Galaxy Fold (April 26), both foldable but without fit in the pocket.
It cost billions of euros development, the appeal is not that great and the price may be prohibitive at least in the first instance for the descent middle class pockets.
The options that are likely to attract the markets are the Xiaomi Mi 9 Launches and Samsung Galaxy S10 Plus, which tend to perform most of the scenarios in use, but with applications that make it easier to use games and Google Play Store faster, and has built-in artificial intelligence capabilities that help improve photos and security.
The Galaxy S10 brings a special 12 MP sensor with wide-angle lens and a 12-megapixel lens with a telephoto lens giving a 2x optical zoom, and the third with a lens of 123º of opening.
The launches bring the most modern chips on the market, Qualcomm’s Snapdragon 855, although in Brazil for cost reasons, at least the Korean, will leave with the Exynos 8920.
The US sale price is $ 999.99 (about 4 thousand reals in Brazil), while the Xiaomi Mi 9 about 450 euros, something around 2 thousand reais, that is, half.
In Europe are available versions with memory of 6, 64 or 128 GB, the folding for now only ads at prohibitive prices: 2 thousand euros, or 8 thousand reais, I think that some manufacturers that will launch with two screens will do well, the experience is almost the same.
The video below gives a sample of Huawei’s Mate X:

 

What characterizes the changes today

07 Mar

In order to change social structures, it was necessary for a long time to mobilize formal structures capable of reacting to structures of power that oppressed the feeling of change in various ways, feeling and emotion were always present, saying that they are emotional now is a mistake, it is due the old idealist separation between objective and subjective motivation.
The virtual is real are coming, not just because of the speed, intensity and quantity of devices able to connect people almost permanently regardless of distances.
The virtual depends on the updating, and therefore is opposite to the current and not the real, even in the space of the imaginary, where the cultural cosmologies are composed, the virtual is close to a cultural real.
What is changing now is that it is possible through the use of communication to establish real (not just virtual) links between people and to mobilize them for a reaction to structures of domination, and those who are unaware that information is available on the net and can being hacked, the last one is the football leaks that shook the world of soccer, by the denunciations of the Portuguese Rui Pinto.
As Manuel Castells explains, social movements have always had at the origin the feelings of shared injustice and indignation, what changes today is that these networked technologies allow a collective subject, but of course this can be negative.
Castells explains that this is not a utopia, but what is happening, and that technology is not decisive, but is influential, as McLuhan says by changing the means and changing communication, change social relations.
The structures of the old state, groups of religious and ideological polarization weaken, and a more real society comes to light than that whose state, for its vices and its virtues appear, the vehicles of communication all controlled by editorial groups and the old ones oligarchies dominated and retained power.
Castells explains this in a 2013 video:

 

Virtual reality, vision and clearing

28 Feb

Mankind has always used shadows to make paintings and to open glades other than for its contemporaries, at least for future generations and for their fellows, the cave paintings, now with the Cavern of Chauvet dates back to 32 thousand BC, can demonstrate this. There are a few ways of writing, and some new ones have been thought by Vilém Flusser, who wrote while speaking of the masks: “The software artist’s mask has not been available for a long time. There may be different levels of creativity. Maybe being a writer will be different from being a software expert, and then perhaps inventing the writer. In this respect, we have prejudices with which to break.” (Flusser, 2014, p.191).

Since Plato’s Myth, the idea of ​​a clearing was theorized by mankind, it is different from cave man because it involves a level of intentionality and creativity as Flusser wants, and more recently the Enlightenment is nothing more than this quest. Heidegger drew attention to the world view, the Weltanchauuun, a set of cultural values ​​that build our vision. The central problem of the clearing is that it can be linked to the senses, so it was for the empiricists, but the fourth dimension (already proven) and other superior ones (that may be) give a new dimension of what this vision is now, with virtual realities, increased and mixed this may be even higher.

There will be no lack of fatalistic and apocalyptic, lacking Flusser’s humility, but immersion is already under way with mixed reality, for which various environments are available to the conventional public, since the word lay can be misinterpreted, 3D viewers and software for creation are available in environments made available by tablet and smartphone manufacturers.

It’s true that just as the new media: internet, web, chats, Pinterest and videos have changed our vision of how to see things, does not mean that changed the world view, but seeing beyond what the senses see we are at least expanding our “sensations,” as Marshall McLuhan wished, in explaining the passage of circular houses, explains by giving an aid to anthropologists: “In the same way, the visualist may not see much difference between the TV film, between a Corvair and a Volkswagen, because the difference lies not between two visual spaces, but between a tactile space and a visual.” (McLuhan, 1964, p. 145).

Flusser, V. (2014) Comunicologia: reflexões sobre o futuro. São Paulo: Martins Fontes.

McLuhan, M. (1964) Understanding media: the extensions of Man. New York: McGraw-Hill. 

The same thing happens now with virtual reality, the augmented and the mixed, nor the moment with the greatest potential to become popular, because what changes is not the field of vision, but the empathic relationship that these media possess, adults may not understand, but to young people this is immediate. An entrepreneur and virtual reality expert explains this empathy, Thong Nguyen’s TEDx is very interesting:

 

 

 

Markham in Canada: smart city

13 Feb

Ignorance of the benefits that smart and rational use can bring to many cities make many public policies inefficient and unnecessarily expensive, a serious problem is the infrastructure to monitor cities. In a partnership project, Bell Canada and IBM Canada want to make the city of Markham,
Ontario in Canada, with approximately 330,000 inhabitants, a model for using networks to make it a “smart city,” according to the Financial Post
The city government will use Bell’s broadband networks and IBM data analysis, collecting sensor data placed throughout the city to decide on investments in various aspects of infrastructure: pipeline leaks, flood-prone regions (Lake Ontario), problems that arise in storms, effective use of energy and tracking.
The projects do not fail to include social improvements and ecological aspects that also depend on the good use of technology and energy,
Many environmentalists are unaware that the results of Medellin were also achieved using Smart Cities concepts, being the first case in Latin America.
South. Similar trials and projects are being conducted in Canada and other parts of the world in view of which a number of multi-provider services may be preparing services that best cost and prevent service disruption.

 

CES 2019 started

09 Jan

The world electronics fair CES (Consumer Electronics Show) began yesterday in Las Vegas and goes until Friday (11/01), what can be seen there?
This year the strongest news seems to be Smart home, smart home, many news, with the advancement of artificial intelligence, the house that already has electronic vacuum cleaner, electronic control of lights and household appliances, will start to talk to you.
Smart TV is already there, and unlike imprisonment, a lot of people have stopped watching conventional TV programs and channels, use them for movies, series (replacing old soap operas) and uses to stream Youtube videos and family filming, this is already in change.
Gradually from the fun this goes to areas of health and interaction, nothing to do with the movie BlackMirrow (see the post), wearable fitness devices and medical equipment for health.
One of the companies present is Neutrogena, which works with skin-related products, covers scanning a 3D human face and creating custom masks for each face, pressure controls, glucose and others are already available in the markets.
But the wiring and gadgets for each is going to change radically, cable-free TV and WiFi-enabled connections are now available, a new type of plug already dubbed a “transformer plug” and the cameras just to watch now can make projections throughout home, including TVs and Web devices for intelligent interaction.
Robots who clean the house and bring things from the refrigerator to you, machines that fold clothes, smart sleeping masks, self-cleaning toilets, were already present last year.

 

What is diffusion of innovation

20 Nov

An innovation to reach the market, if it does not fall into disuse that is a possibility, goes through a process called “adoption curve”.
Everett Rogers, is a recognized in this area of communication studies, professor of department and journalism of the University of New Mexico, his book Diffusion of Innovations, already 5ª. is one of the most cited books in the area, the first is from 1962, and the author died in 2004.
Their main argument is that innovation is communicated over time among participants in a social system, and the origin of their theory spans several disciplines and although it has never used the term, it can be safely stated that it is transdisciplinary.
Rogers proposes that four main elements influence the dissemination of a new idea: innovation itself, communication channels, time and a social system. This process depends heavily on human capital. Innovation must be widely adopted to sustain itself. Within the rate of adoption, there is a point at which an innovation reaches critical mass. That can also be understood as the curve of adoption
The theory characterizes 5 advantages for adopting a technology: 1) the advantage of improving an innovation over a previous generation competitor of a product, 2) from a point, a team must improve the advantage relative to its competitor in potential for there to be no return to the previous product, 3) the new product must be compatible with the previous one, not only when installing and operating, but especially with regard to the potential consumer’s lifestyle, 4) relevancy at the time of launch which means a deep understanding of the conditions that innovation finds in the moment it is launched, and 5) what is the complexity or simplicity of using innovation when it is launched, complex innovations can reach a small audience only.
An innovation to reach the market, if not fall into disuse, is a possibility, goes through a process With its successive groups of consumers adopting the new technology (shown in blue), its market share (yellow) will eventually reach saturation level.
