Qutrit, teleportation and philosophy
12
Aug
Two teams independently managed to teleport quantum particles called 
QuTrit (quantum trit), with a few days difference that can be said to be simultaneous.
Both are awaiting review of the peer review process for their publications to come out and receive “invention” credits.
A qutrit is similar to the qubit (the well-known quantum bit), except that instead of binary beings (0 and 1) they are classic ternary systems, which because they have the possibility of a third state, say 0, 1 and 2 can transform more information than qubit.
This surpasses what in philosophy, especially the idealist in which we can have only A and B, and there can be no contradiction, in this case not exactly contradiction, but a third state.
The communication system used is the HD-BSM (High Density Bell State Measurement).
Although quantum systems are much less noisy (subject to change by the environment) than digital electronic systems, qutrit are even less noisy and thus more reliable.
Teleportation means that information goes from point to point without a “medium” meaning that it will be less subject to interception and thus more reliable in terms of quantum cryptography.
The two groups claiming to have a healthy scientific rivalry are the group led by physicist Guang-Can Guo of researchers from the University of Science and Technology of China, and the other led by Anton Zeilinger of the Austrian Academy of Sciences, and there is already a version in analysis of the articles on the subject, the so-called pre-print, and were published respectively on April 28 (preprint) and June 24 (preprint).
From biopolitics to psychopolitics
10
Aug
The form of power, while still centered on the state and its modern concept of state
that comes from Hegel and not just the French Revolution, underwent changes in the 19th and 20th centuries, which philosopher Michel Foucault called biopower.
Literally the philosopher elaborates it this way: “The instruments that the government will give to achieve these ends [that are, in some way, immanent to the field of the population, will essentially be the population over which it acts. ” (Foucault, 1978, p. 277-293) that is in his work Microphysics of power, when it addresses the issue of governability.
Many who do not accept Foucault’s philosophy, for lack of reading or understanding, do not realize that what today is called public policy has this idea at its source. However biopower can be thought of more fully, including technologies that act on a local population or particular social demand, but always with the idea of establishing power and control over particular localities or social groups.
Byung Chul Han in three recent works (The Swarm, Psychopolitics, and What is Power) (explains that this form has been superseded by current psychopolitics, where local powers and policies are replaced by elaborate new techniques of power, Foucault also calls them that. With the problems of health, birth, mortality and life estimation (see this theme in welfare reform) the biopolitics aimed to control the “body” as well as the biopower.
Entering the digital age this evolves into psychopolitics, which leads us to a crisis of both freedom and identity, where psychically even one’s own will is struck. Byung Chul Han’s long analysis of What Is Power, returning to Nietzsche and even Kierkegaard (1813 – 1855), the philosopher reveals the subjective aspects that power has been working from the conception of the modern state.
He considers it essential to understand the digital age, even though he has criticism of technological appropriation, and places the latest Big Data technology as a key element in this process, and is therefore very current because it is the technology that reaches the psyche of the social subject, and of the individual ultimately: his interests, desires and worldviews.
I consider it important to return to Kierkegaard, although Chul Han does so on time, the ideas of this existentialist philosopher are deeply related to the concepts of the works of the Korean-German, in particular: the anguish in The Society of Bournout and the pursuit of happiness and pleasure in The agony of Eros.
The social scientist slovenian Renata Salecl’s obsession with choice addresses the issue of Kierkeegard’s updated anguish:

Anguish between inter-times
17
Jul
The passage from one historical time to another is tragic and is subject to many anguish,
upheaval and that cause throughout society a great anguish: the new one does not exist yet and the old one takes to leave.
However, it is possible to read in the literature and in the various social theories how this passage, sometimes violent and sanguine like the French revolution and sometimes an explosion of culture and of knowledge like the renaissance.
Nicolau Sevcenko, who also analyzed the Renaissance period, analyzing the current moment as a roller coaster, and a stage that is in the roller coaster series, is described as: “it is the climax of precipitous acceleration under his intensity “relaxes our impulse to react, delivering the dull points” (SEVINCENO, 2001, p.16).
This author is nice to note that the crises of the previous deity, he said about the Italian renaissance: “The history of Renaissance culture clearly illustrates the whole process of cultural construction of modern man and contemporary society. In it, the germs of individualism, of rationalism and unlimited ambition, of the most imperative and representative behaviors of our time manifest themselves, already very dynamic and predominant. ” (SEVCENKO, Nicolau, The Renaissance, São Paulo: Current, 1987.)
That is, they are already a culture of our rhythm, parallel to renaissance, elements of a new culture, an approach to the planet as a whole, such as different ethnic and religious cultures, the end of individualism with collective responses. , but there are some old things.
The social anguish provoked by these changes, when they touch on certain people and with the immunity to the various types of social manifestation that arise from the provoked crises, can become a social disease, a political psychosis and an ataraxia to respond to the impulses provoked by groups of pressure.
The Greeks called ataraxia a state of “stillness of the soul,” the pre-Socratic philosopher Democritus (460-370 BC) who introduced this term in philosophy, was adopted by Epicureans and Stoics, but also has a sick state that would be indifference or apathy. It is necessary, above all, for calm and dialogue, which must also be done between tradition and the new cultures that emerge.

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 work of Lev Manovich
02
Apr
The what differentiates Manovich from other discourses is his understanding of
computer language and his study of interfaces, this was reflected in his works such as the one presented at the Chelsea Art Museum in New York, the Finnish Zentrum für Kunst und Medientechnologie in Karlsruhe, at The Walker Art Center (Minneapolis) and at the Museum of Contemporary Art Kiasma (Helsinki).
He has received numerous awards such as the Guggenheim Fellowship and the Digital Cultures Fellowship (University of California, Santa Barbara) and has been a reference professor of digital art at the California Institute of the Arts and the University of Arts and Design (Helsinki) and Arts Center Hong Kong), with a universal vision, therefore.
Without ignoring conventional readings and media, he shows that the reformulations of the categories for analysis of the current models function as a sort of genealogical map of the new media (I would say anthropological, but I understand the perspective of the author), where he seeks to sketch the possibilities and perspectives of the future.
In this way, both the perspective of the computer and its productive potential appear to be linked to its work as mediator of culture.
It appears in Manovich’s text: “Each stage in the history of computer media presents its own aesthetic opportunities as well as its own projection of the future: in short, its own ‘research paradigm’ “(Manovich, 2001).
And it points to the future by saying that some techniques: “At a later stage, these paradigms will be modified or even abandoned.
In this book, you wanted to the “new media research paradigm, during its first decade, before it falls asleep in invisibility,” which is where the ideas of interfaces should break.
The good self-presentation is this keynote: Museum without Walls: Using Big Cultural Data to Re-think Cultural History – Lev Manovich, in The Graduate Center, City University of New York, see the vídeo:
Good trip! Passengers to space

Elon Musk after revolutionizing the Tesla car, here in Lisbon I got in and I’m
trying to test drive, after the revolutionary solar battery (do not adopt because of the electric and diesel trusts), now the first space travel with passenger was made.
The SpaceX spacecraft, the first of a private project whose $ 250 million cost is a quarter of NASA’s cost, and has already docked at the orbital station on a quiet trip, still no passengers.
The tourist who paid part of the project is Yusaku Maezawa, a businessman who sold some in the mail and today has a clothing sales site called Zozotown, his identity was a long time in secret, Tesla’s BRF (Big Falcon Rocket) ship is reusable and was propelled by the Falcon 9 rocket, and should return to Earth in a week.
Maezawa’s project called DearMoon involves artist he enjoys and it’s a futuristic poetry without fail to have a business side.
SpaceX plans to reach Mars in 2022.
The details of the 8 tickets bought by Maezawa and her artistic dream are:
Line art, 3D and tesseract

The fact that contemporary culture is based on a science, an art and also an ethical and aesthetic dimension based on 
geometry has built an ideal model of nature, man and society, which is purely ideal and unrealizable to man.
It seems a post-humanism, since contemporary humanism is that of the Kantian categorical imperative: “Act as if the maxim of your action should become, through your will, a universal law”, sometimes the ” through his will, “but the imperious fact remains there, to become a model for others, narcissism and pre-humanism.
All this came from the idealism and absolutism of mathematical geometric ideas, it is not abstractionism since this current in both art and mathematics itself has in fact become much more revolutionary than it seems, the Hausdorff dimension and the fractals, as well as the mathematical and physical hypotheses about entropy prove this importance.
Physics in discovering the fourth dimension refers human thought and adventure to an unthinkable space, the intergalactic voyages, begins to draw the history of the universe itself, how supernovae form, what are black holes and black matter, finally a threshold of a new time, born of quantum physics and the fourth dimension.
What this has to do with art, with technology, absolutely everything, since the human vision and sensation widen, while many get into dogmatic holes, some even redeclarate the flat earth, the dimension of the infinite, the cosmogonies and the fourth dimension emerge
All this seems theoretical, but it was Carl Sagan in his famous Cosmos series, now available online, which explained all this in a simple and accessible way to all, follows a piece of your video in which explains this:
An immersive digital exhibition
18
Feb
Paris is famous for the Louvre, Orsay and Grand Palais museums, it also has
a digital art space, called Atelier des Lumières (photo), a fair tribute to the Lumières brothers.
His great attraction that starts now is an Immersive Van Gogh Exhibition, which has inspired so many inspirations, the film Akira Kurosawa’s Dreams, various types of animation, and a lot of art was inspired by the genius of the Netherland.
The space debuted with Gustav Klimt’s exhibition and quickly caught the eye.
Van Gogh is known, but Gustav Klimt (1862-1918) is not so curious, the connection of the two with this house of Digital Media Art, both opposed to realism (would say to realistic objectivism, but anyway …) and also the positivism that penetrated different humanities, art did not escape.
One can also link it with Art Nouveau, its movement in another direction arose from a work commissioned by a wealthy Belgian Adolphe Stoclet, who had a palace built by leaving him in charge of Wiener Wekstratt, of the Viennese Atelier, where Klimt was an exponent .
The style now appears with repetitive geometric styles, letting appear some realistic parts (that is to say …) that allow the understanding, there uses a Byzantine style cover, and mosaics where realism and abstraction are in contrast, and finally its style.
Returning to Van Gogh’s immersive exhibition that takes place at the Atelier des Lumières, the exhibition begins now in February and runs through December 2019.
The video below gives a sample of the exhibition, with presentation of the co-director of the exhibition Gianfranco Iannuzzi.
Fake news with few days
12
Feb
False, malicious or biased news are old, we have already mentioned the
allegations made by Karl Kraus, also news that actress Rita Hayworth (the stage name of Margarita Carmen Cansino, famous in the 50´s and 60´s), who would have lived another two years , or the misleading advertisement that Nike would be giving shirts of the Brazilian national team.
Now there is software developed by the research company Fraunhoffer-Gesellschaft, in Germany that has developed a system that automatically analyzes post of social media and filters false news and misinformation, we can predict a promising future.
It is worth mentioning that this was thanks to the new technologies, the tool does a machine learning that filters the news and through learning (in the sense of algorithms per machine) analyzes contents and metadata, verifying user interaction and optimizes results in real time.
The tool also checks the amount of data (viralization processes), with sending data graphs, frequency and follower networks.
Ulrich Schade, according to the Fraunhofer website, said: “Our software can be customized and trained to meet the needs of any customer. Our software can be customized and trained to meet the needs of any customer. For public agencies, it can be a useful early warning system.”
Metadata are used as markers, thus allowing fake postmarking, that is, it plays a crucial role in differentiating between authentic sources of information and false news.
So if a site with a certain frequency of posts is made, how often and how a tweet is scheduled and at what time? The time of a post can be very revealing, as well as the frequency of the tweet and the followers.
It should also reveal the country and the time zone of the originator of the news for its correct identification and location, therefore the hours are essential.
A high frequency of sending suggests bots, which increases the probability of a false news, can be easily detected and can signal a fake.
Social bots generally send their links to a large number of users, and this is an example of how to spread the uncertainty among the public, so never give in.
Connections and account followers can also be fertile ground for analysts, although well-intentioned people use it, the chance to be a fake is great, and now a tool can detect it, fake days are counted.
The truth in times of crisis
31

The new hermeneutic consciousness, the chance to establish dialogue between 
concepts, make man more vulnerable to a crisis of thought, is more orthodox and predisposition to an intolerance, a truth of the Monarchy of Fear how to define Martha Nussbaum in his new book , favorite us in dictatorships and extremes.
But what is this new consciousness? defines Hans Georg-Gadamer thus: “Hermeneutic consciousness, which must be awakened and kept awake, recognize that in the age of the philosophy of science, the claim of superiority has something chimerical and unreal about it.” (Gadamer, 1975)
And he inclines: “But the will of man who is farther than ever, more than the former sensation, a point of becoming a utopian or eschatological sensation, a hermeneutic consciousness of finding with this will something true of the recording: which is still and never more real. ” (Gadamer, 1975)
That is, an a-lethe, not forgetting. The focus of subjectivity in the face of objectivity is a true dark window: “The focus of subjectivity is a brilliant upheaval.” (Gadamer, 1975).
Self-consciousness is Individual case is only a closed movement of historical life, remembering that self-consciousness is the great Hegelian construct in relation to the historical rule. What happens to history is that we put them in more than the crisis of idealistic and scientific thought, or the neo-positivist methods are there, phronesis.
For Gadamer, Phronesis, the tailary practice, emerging between ethos and the logos, directed for higher and one third year to excluded between the I and us.
Gadamer says: “Understanding is not something that tries to intercept what one wants to say when one asks oneself about what is happening?” (Gadamer, 1975), in of the common horizons and reorganizes the discourse.
This is very difficult today, but not impossible, if there is a minimum of trust between two discourses, but positive science, dogmatism, fundamentalism and other isms do not admit this, are entrenched in their “self-consciousness” arrogating practical (it is empirical in general) or collective (closed circles).
