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.

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:

 

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.

 

Why did artificial intelligence emerge?

22 Aug

The long road covered by Artificial Intelligence includes the construction of languages such as Lisp, Prolog, Haskel, but environments like DialogFlow, Watson, and
At the end of the 20th century there was a major crisis in AI, but the emergence of researchers in the Semantic Web resumed study and gradually, subjects like IoT (Internet of Things), Natural Language and Machine Learning (there is no translation, but we could say learning by Machine) emerged.
The fact that scares some is linked to the concept of “intelligence” and “mind.”
This emergency has awakened the five largest technology companies in the world: Apple, Microsoft, Google, Amazon, and Facebook, which have started investing in smart people who can talk to humans.
Now 28% of consumers in the United States currently use some virtual assistant, these devices that integrate the AI technology of a voice assistant with a common home product has had great success, such as Alexa, Echo and Google Home, but the increase of sales to 39% annually were celebrated by companies.
In companies the concern for privacy, the operation is done using cloud storage, companies with sound assistants use different measures to protect the personal information of their consumers, but know that there are flaws in these defenses.
The audio sent to Google and Amazon is encrypted before being transmitted, leaving the data exchange supposedly safe, but the people database needs to be accessed in order for the machine to “develop” its learning ability.
Recently a researcher in the field of information security has demonstrated that it is possible to transform an Echo manufactured before 2017 into a perpetual recording instrument whose audio can be transmitted to a remote location without the user knowing.
To protect yourself from hackers, a good practice is to access your account and erase history of interactions with the services from time to time, but it remains to be seen if it has not been hacked in this period.
Apple’s Siri, instead of associating the recording with the user account, associates the collection of the interaction with you with a series of random numbers.
With or without security, this market has grown and companies are watching, it is irreversible.

 

Material can help quantum chips

08 Aug

Researchers at the University of Central Florida (UCF) have discovered a type of material that could be used as a “building block” of quantum chips, consisting of hafnium, tellurium and phosphorus, Hf2Te2P.
According to UFC researcher Madabe Neupane, “Our discovery takes us one step closer to the application of quantum materials and helps us gain a deeper understanding of the interactions between various quantum phases.”
The material has more than one electron pattern that develops within its electronic structure, giving it a range of quantum properties. Neupane says that this material will increase computing power for large volumes of data on new devices and will considerably reduce the amount of power needed for power electronics.
The discovery has already attracted companies that are investing in research, Microsoft for example invested in its project called Station Q, the laboratory that is dedicated to the field of topological quantum computing, and Google has teamed up with NASA in an investment that works with quantum computing and artificial intelligence.
Because quantum phenomena need to be better understood so that electronics are totally replaced by photonics and quantum computation, computational scenario changes tend to change rapidly and continuously.
The discovery of Neupane’s lab is published in Nature Communications, and is a big step forward for this change of scenario.

 

News in Google News

02 Jul

After several announcements, finally in the second half of May Google launched its new application, only now I have been able to take a look at the application that replaces Google Play Nwesstad, now with use of Artificial Intelligence.

The application works on using machine learning to train algorithms that scour complex and recent news stories and divides them into an easy-to-understand format with timelines, local news and stories presented in a sequence according to the evolution of the facts, for example , the start of a football match, its most important bids, the result and the consequences.

This section which are news that the algorithms think important to you have the name For You, follow 3 more sections so divided: The second section is called Manchete, where the latest news and specific topics are presented. Here is a subsection where you can choose to read the news through Full Coverage by Google, where Google splits it into items from a variety of social media sources, letting you know where and when it happened.

The third section shows favorites, such as the top topics the user usually accesses, the AI ​​has great work there, goes to the owner’s favorite sources, saves stories for later readings, and saves searches according to the location of the texts.

And finally the White Play (White Play) which is the addition of the new Google news, which allows the user to access and subscribe services with premium content in news sites.

While a part of the critique continues to duel with the old canned news schemes linked to editorial groups, the world of personalized news evolves

 

 

Alexa: Amazon personal assistant

26 Jun

It may not seem like a new phenomenon in technology since there are wizards like Siri, Cortana or Google Now, but the fact that this wizard is really personal, that’s why I called the others for voice assistants, is the fact that it learns and stores the data in a private cloud from Amazon Web Service (AWS).
These personal assistants although all grounded by the use of voice there are differences, they can learn from specific people habits and functions they desire, while the voice assistant, as I call Siri and Google Now now empordered by Dialogflow, as we explained in the post above, they can respond and learn from human interaction, but may, if it is desirable to organize their own database.
Alexa (because I’m the personal assistant I think is masculine, but it can be the same) is centralized in the Amazon cloud and has its own equipment that is Amazon Echo, a column always connected to the Internet via WiFi that is attentive to dialogues of its “owner”.
Streaming music services using Spotify or Pandora, you can read the news of the main newspapers you prefer, inform the weather forecast or the traffic on the way to work, can control all equipment at home that are Smart Home, including it can identify and tell about compatibility, plus its capacity goes beyond.
In addition, it promises to check basic things like solving math accounts or getting into a conversation and even telling jokes, over time this bank and this ability will evolve.
But beware, we have already written here about the myth of singularity (especially the book by Jean Gabriel Ganascia), the idea that this will turn a monster and control you is less true than to individualize and stop talking to friends and relatives

 

Make holograms real, fast and accurate

20 Jun

We have already mentioned the development of holograms in space without the need for devices that recreate the artifacts, now it is possible to do them in an ultra-fast and very precise way. Scientists at the Lawrence Livermore American Laboratory in California have developed a technique that can create complex objects in seconds, we can say using Shannon’s sampling theorem for imaging, now being three-dimensional.

This technique creates the objects in layers simultaneously, the details were published in the journal Science Advances in December 2017, there are two really important innovations there, the possibility of creating real images in ultra-fast mode using a photosensitive resin recreating 3D printing with a powerful laser which hardens this resin making it a plastic.

This can also be done with metals using electron beam and a metal powder instead of the resin, so does not need the numerous supports required for 3D printers. LLNL engineer Maxim Shusteff, who leads the study, told New Atlas: “The fact that you can make totally 3D parts, everything in one step really overcomes a problem in additive manufacturing”, now holograms can return to material parts.

Another option would be live tissue bio-printing: “We made a good first attempt,” Shusteff said, “but we have not yet taken it to the limit of its performance, so the space is open to us and others to demonstrate what this approach is able to do. “living tissue bioprinting. “We made a good first try,” said Shusteff,

If 3D printing was already heralded as a revolution, this new technique promises to further accelerate this process
