#Payer_la_terre. À la rencontre des premières nations des #Territoires_du_Nord-Ouest_canadien
https://www.futuropolis.fr/assets/media/cache/cover_medium/gallimard_img/image/790593.jpg
En 2015, Joe Sacco s’est rendu par deux fois dans les territoires du Nord-Ouest du Canada, au-dessous de l’Arctique. Il est allé à la rencontre des Denes, un peuple autochtone. L’auteur nous raconte l’histoire de ce peuple, ses traditions, restées intactes pour certaines, les premières rencontres avec les Anglais.
Pendant longtemps, les peuples indigènes du Grand Nord, vivant sur des terres non propices à la colonisation agricole, restèrent livrés à eux-mêmes, jusqu’à ce que la découverte de pétrole et d’or incite le gouvernement à officialiser son autorité sur eux, comme sur leurs terres. À cette période, les autorités s’appropriaient les territoires, non plus par les massacres, mais cliniquement, méthodiquement, et de façon administrative – grâce à des traités.
En lisant ceux-ci, on n’échappe pas à l’impression que les « Indiens » ont donné la terre où ils vivaient en échange de la promesse d’une annuité de quelques dollars, de quelques outils et de médailles pour ceux qui se disaient leurs chefs. Aujourd’hui, la fracturation hydraulique ajoute la pollution à la spoliation initiale.

  ’My work is not finished’ : #François_Paulette named officer of Order of Canada
  Denesuline elder has long advocated for Indigenous and treaty rights
  Denesuline Elder François Paulette has many accomplishments under his belt. He’s an educator, activist, spiritualist, father, grandfather, former chief, and a traditional knowledge holder.
  Now he can add one more title to his name — officer of the Order of Canada.
  The national order recognizes people who have made extraordinary contributions to the country. Paulette is among 120 people — six from the North — who are being honoured this year. He is being recognized for his longtime contributions to treaty and Indigenous rights and his promotion of circumpolar health research.
  “My biggest job has always been protecting the Earth and the water. And that’s always for the future of the children. And also the rights of Indigenous people, treaty rights,” he said.
  But Paulette, who is a member of the Smith’s Landing First Nation, said he’s not one for medals and awards. When he learned he was an Order of Canada recipient, he said he had to think about whether or not to accept the honour. He ultimately decided to do it for his 10 grandchildren.
  https://i.cbc.ca/1.5413290.1577999308!/fileImage/httpImage/image.jpg_gen/derivatives/original_1180/francois-paulette.jpg
  “It’s not in my blood to get recognition, at least from the Canadian government or the Crown for the work I’ve done, because my work is all about protecting Mother Earth and working on rights of Indigenous people,” he said.
  For Paulette, one of his proudest accomplishments is moving back to his home community where he and his wife built a log home and raised their children in a contemporary-traditional lifestyle.
  “It was a sense of renewal for me,” he said.
  Paulette was born in April 1949, near Fort Fitzgerald, Alta, and lived there until his community was relocated to Fort Smith, N.W.T., by the federal government beginning in 1959.
  Paulette said he’s also proud of his work negotiating outstanding Crown treaty obligations.
  In 1969, Paulette was one of the founding members of the Indian Brotherhood of the Northwest Territories — renamed the Dene Nation in 1978 — which was formed in opposition to The White Paper. That federal document proposed terminating existing treaties and assimilating Indigenous people in Canada.
  A turning point for the Dene
  In 1971, Paulette became the youngest chief in the territory at that time. The following year, he was part of the Paulette Case, something he said was a “turning point for the Dene.”
  In that case, Paulette and 16 other chiefs from the Mackenzie Valley, challenged the Canadian government to recognize Indigenous title to over 1,165,494 square kilometres of land in the N.W.T. They filed a caveat arguing the Dene didn’t surrender their rights or land when they signed Treaty 8 and Treaty 11 and sought to prevent construction of the proposed Mackenzie Valley Gas Pipeline.
  https://i.cbc.ca/1.5413281.1577999288!/fileImage/httpImage/image.jpg_gen/derivatives/original_1180/francois-paulette.jpg
  In 1973, Supreme Court Justice William Morrow ruled that the chiefs had established a case for claiming rights to the land. While the ability to register the caveat was overturned by the Supreme Court of Canada, Morrow’s findings regarding Indigenous rights were upheld. The case also helped prompt the Berger Inquiry, which led to a moratorium on the proposed gas pipeline.
  “I think that turned the page of how the Dene were to begin to negotiate … Canada’s outstanding obligation to the First Nations,” Paulette said.
  https://i.cbc.ca/1.5413284.1577999316!/fileImage/httpImage/image.jpg_gen/derivatives/original_1180/francois-paulette.jpg
  Paulette said he is also proud to have been one of the delegates that travelled to Geneva, Switzerland, in 1977, to begin talks that led to the United Nations Declaration on the Rights of Indigenous Peoples.
  “That was nice to see that eventually unfold and be recognized by the world.”
  Since then, Paulette has been involved with the Institute for Circumpolar Health Research and is now an adjunct professor at the University of Alberta’s School of Public Health. He has also travelled around the globe speaking to people about Indigenous and treaty rights, spiritualism, healing and environmental protection.
  “If this little token of, this Order of Canada can elevate my profile, I will continue,” he said. “My life in that way is not going to change, my work is not finished.”
  Paulette will be honoured by the Order of Canada at a ceremony in Ottawa later this year.

Quantum Computing Gets Hardware Boost With Spin Glass Breakthrough
▻https://www.techrepublic.com/article/quantum-computing-d-wave-spin-glass-advantage
https://www.techrepublic.com/wp-content/uploads/2023/04/particles-gcbe841619_1280.jpg
One of the challenges in quantum computing is overcoming 3D spin-glass optimization limitations, which can slow down quantum simulation meant to solve real-world optimization problems. An experimental solution is D-Wave’s Advantage quantum computer, running spin-glass dynamics (essentially a sequence of magnets) on 5,000 #qubits.
[…]
The main takeaway for enterprises is that spin-glass computing on a #quantum_annealing device may eventually be able to efficiently solve optimization problems, achieving a goal with as little energy as possible. For example, it could be a relatively efficient way to answer questions such as “Should I ship this package on this truck or the next one?” or the ‘traveling salesman problem’ (“What is the most efficient route a traveling salesperson should take to visit different cities?”), as D-Wave wrote.
D-Wave is one of the only companies that offers enterprise #quantum_computing space with both gate and annealing programs, which now includes its 5,000 qubit, commercial-grade Advantage quantum computer. There is still some question as to how practical this technology is, but the new paper is proof that further commercial quantum computing optimization can be performed on D-Wave’s hardware.

Quantum annealing - Wikipedia
(pas de vf)
▻https://en.wikipedia.org/wiki/Quantum_annealing
Quantum annealing (QA) is an optimization process for finding the global minimum of a given objective function over a given set of candidate solutions (candidate states), by a process using quantum fluctuations. Quantum annealing is used mainly for problems where the search space is discrete (combinatorial optimization problems) with many local minima; such as finding the ground state of a spin glass or the traveling salesman problem.

  Petite confusion dans l’article de techrepublic et dans l’article wikipedia, qui mentionne le problème du voyageur de commerce comme étant un problème d’optimisation. C’est faux. Le problème du voyageur de commerce est un problème de décision (un problème dont la réponse est oui ou non).
  Définition possible (empruntée à l’excellent "complexity zoo") : « Given a set of n cities, and the distance between each pair of cities, is there a route that visits each city exactly once before returning to the starting city, and has length at most T ? »
  ▻https://complexityzoo.net/Complexity_Zoo:N#np
  Alors vous me direz : il y a bien une histoire de longueur à optimiser. Oui et non : répondre au problème ne signifie pas nécessairement exhiber une solution.
  Après ça, à chaque problème de décision on peut associer un problème d’énumération permettant d’énumérer les solutions du problème. Et dans le cas du voyageur de commerce, ça nous donne un problème d’optimisation (j’énumère en essayant de converger vers le minima d’une fonction objectif).
  Bon et sinon sur ces histoires de quantum computing, c’est vachement intéressant mais pour l’instant on reste un peu sur sa faim. Le jour où on résoudra le problème SAT en un claquement de doigt ça commencera à m’intéresser :o).

A monolithic immersion metalens for imaging solid-state quantum emitters.... Quantum emitters such as the diamond nitrogen-vacancy (NV) center are the basis for a wide range of quantum technologies.However, refraction and reflections at material interfaces impede photon collection, and the emitters’ atomic scale necessitates the use of free space optical measurement setups that prevent packaging of quantum devices. To overcome these limitations, we design and fabricate a metasurface composed of nanoscale diamond pillars that acts as an immersion lens to collect and collimate the emission of an individual NV center. #monolithic #immersion #metalens #imaging #solid-state #quantum #emitters #photonic #optic #physics #chemistry #diamond #nitrogen-vacancy #NV #light #technology #hardware (...)

This article was written by Ben Perez and originally appeared on the Trail of Bits Blog. It is being republished with permission of the author and includes additional notes & comments from researchers at the RI lab.For many high-assurance applications such as TLS traffic, medical databases, and blockchains, forward secrecy is absolutely essential. It is not sufficient to prevent an attacker from immediately decrypting sensitive information. Here the threat model encompasses situations where the adversary may dedicate many years to the decryption of ciphertexts after their collection. One potential way forward secrecy might be broken is that a combination of increased computing power and number-theoretic breakthroughs make attacking current cryptography tractable. However, unless (...)

IntroductionAdvances in computing require appropriate hardware. Though computers have become smaller and more powerful over time, the power of regular computers (also known as classical computers) is limited.Quantum computers are a new generation of computers built to solve the problem of exponential scaling (for example, finding the optimal solution to a problem in which there are too many possibilities for a classical computer to analyze).Background on Classical ComputersClassical computers have many components (including main memory, arithmetic unit, control unit, and others). They represent, process, and control data through these components. Computer chips contain modules, which include logic gates, which in turn include transistors.A computer module is a collection of electronic (...)

But quantum physics is a magnitude more complicated, explaining abstract theories in mathematical terms rather than in visible realities (in the sense that code is a visible reality). Quantum physics requires a depressingly-wide foundation of knowledge in order to offer up more than a recapitulation of (...)

Far more powerful and capable of a great deal more than ‘traditional’ computers, quantum computers may be the natural next step in technological development. However, they also pose a considerable risk to existing #cybersecurity measures.Here, we take a look at whether developments in quantum computing and quantum cryptography will result in the creation of appropriate security technology, or whether they will put individuals, businesses and governments in unprecedented danger.The RisksModern cybersecurity is largely based on the practice of cryptography. Simply put, this is the use of large numbers and complex calculations to create complex keys that cannot be cracked easily. However, quantum computers’ ability to perform certain calculations at a much faster rate may render such (...)

We’re all (at least slightly) familiar with the concept of machine learning and AI by now — but just what exactly is quantum computing? If you aren’t scrolling SlashDot and TechCrunch on the daily, quantum computing may have escaped your tech dictionary. The name alone evokes some notion of a complex, sci-fi super-computer type of setup. And guess what? That’s not far off the mark.We sat down and had a chat with two experts delving into the AI/Quantum computing sphere, Amit Bansal, Managing Director, Analytics Delivery Lead APAC & Artificial Intelligence Delivery Leader at Accenture and Vaibhav Namburi, Director of Five2One & Dveloper.io to enlighten us about what’s in store for the future.What is quantum computing?Let’s preface this by saying that we’re not going to go into the finer (...)

Who will win the World Cup? In 2010, we had an octopus to help us. In 2014 we had to actually watch the games to find out. But this year, we have quantum computers.Though quantum computers will be good at many things, predicting the outcomes of sports games will not be one of them. But let’s not allow silly things like facts to hold us back. Let’s do it anyway!I took the flags of all participants in this years world cup and gave them a name in binary. The first three bits of these names tell us the group they are in (000 for group A, 001 for group B, etc). The last two bits tell us where they were in the group before the competition began (00 for top, 11 for bottom, etc). So it’s a fairly sensible and not entirely arbitrary binary encoding.Then I told a quantum computer to create a (...)

Quantum Computing…sounds mind blowing already.It seems like another huge buzzword I get it, but whats all the hype? Why are super smart people spending their time developing and researching quantum computers?Companies like Google, Microsoft, IBM and super successful startups such as D-Wave and Rigetti Computing are investing millions and millions of dollars into quantum computers.Why? Because they are building the world’s most powerful computer to ever exist.Before I tell you how Quantum Computing will disrupt the healthcare industry, lets get you caught up with what the heck it is.In short Quantum Computers use phenomenons called superposition and entanglement to create qubits with special computational power determined by the laws of quantum mechanics.Qubits are unlike binary bits, (...)

An example of the future of quantum computers, created out of their past.Many people have contributed to quantum physics over the last century. Through their work, we now have an immense understanding of the quantum realm. And we can control it to make new and better technology.One emerging example is quantum computing. Prototype devices are getting ever bigger and more powerful. And they are even available on the cloud for anyone to experiment with.I decided to use one of these cloud based quantum computers to celebrate the giants on whose shoulders we stand. I took images of 16 Nobel prize winning quantum physicists, and I combined them.I did this using quantum superposition. This is a phenomenon which effectively allows a quantum system to be doing multiple things at once. (...)

"Quantum superpositions of distinct coherent states in a single-mode harmonic oscillator, known as “cat states”, have been an elegant demonstration of Schrodinger’s famous cat paradox. Here, we realize a two-mode cat state of electromagnetic fields in two microwave cavities bridged by a superconducting artificial atom, which can also be viewed as an entangled pair of single-cavity cat states. We present full quantum state tomography of this complex cat state over a Hilbert space exceeding 100 dimensions via quantum non-demolition measurements of the joint photon number parity. The ability to manipulate such multi-cavity quantum states paves the way for logical operations between redundantly encoded qubits for fault-tolerant quantum computation and communication."

  The basic premise of the #quantum_reconstruction game is summed up by the joke about the driver who, lost in rural Ireland, asks a passer-by how to get to Dublin. “I wouldn’t start from here,” comes the reply.
  Where, in quantum mechanics, is “here”?

  A further approach in the spirit of quantum reconstruction is called #quantum_Bayesianism, or #QBism. Devised by Carlton Caves, Christopher Fuchs and Rüdiger Schack in the early 2000s, it takes the provocative position that the mathematical machinery of quantum mechanics has nothing to do with the way the world really is; rather, it is just the appropriate framework that lets us develop expectations and beliefs about the outcomes of our interventions. It takes its cue from the Bayesian approach to classical probability developed in the 18th century, in which probabilities stem from personal beliefs rather than observed frequencies. In QBism, quantum probabilities calculated by the Born rule don’t tell us what we’ll measure, but only what we should rationally expect to measure.
  In this view, the world isn’t bound by rules—or at least, not by quantum rules. Indeed, there may be no fundamental laws governing the way particles interact; instead, laws emerge at the scale of our observations. This possibility was considered by John Wheeler, who dubbed the scenario Law Without Law.
