Google has solved problems in two hours that would take three years on a supercomputer. It’s the quantum advantage we needed

by

Google has taken a notable step into the field of quantum computing with a new algorithm called Quantom Echoes. This algorithm has been able to demonstrate for the first time a “practical and verifiable quantum advantage” that makes its quantum computer make fools of today’s large supercomputers. 13,000 times faster than a supercomputer. The new algorithm, called Quantum Echoes (“Quantum Echoes”), has made it possible to demonstrate that a quantum computer – based on Google’s Willow quantum chip— successfully executes a verifiable algorithm that exceeds the capacity of today’s large supercomputers. Thus, that computer managed to execute that algorithm 13,000 times faster than the best current classical supercomputer when executing similar code. “Quantum verifiability”. Google’s quantum supercomputer solved the problem in just over two hours, when in the second supercomputer most powerful in the world, Frontier, would have taken 3.2 years. But it also did it in a verifiable way: the result can be repeated in the quantum computer itself or in any other of similar caliber. Quantum echoes. The algorithm resembles an advanced echo: you send a signal to the quantum system, perturb a qubit, and then precisely reverse the evolution of the signal to “listen” to the resulting echo. This echo is special because it is amplified by constructive interference, a quantum phenomenon where waves add up to become stronger, which allows this effect to be precisely measured. The algorithm allows modeling the structure of systems in nature, from molecules to black holes. An achievement with a lot of Nobel Prize behind it. The milestone is based on decades of research in this area, including that carried out by the recent Nobel Prize winner, Michel H. Devoretwho is part of the Google team. Together with his colleagues John M. Martinis and John Clark he laid the foundations for this advance at the University of California at Berkeley in the mid-1980s. “Quantum verifiability”.

His discovery: the properties of quantum mechanics could also be observed in electrical circuits large enough to be seen with the naked eye. That gave rise to the creation of superconducting qubitswhich are the basic blocks with which Google has created (like other companies) its quantum computers. Devoret joined Google in 2023, thus strengthening the company’s trajectory in its search for the now famous “quantum supremacy”. Promising practical applications. The advance is directed directly to the solution of important problems in fields such as medicine or materials science. Quantum computing remains an experimental technology and faces a key challenge with error correction, but Quantum Echoes demonstrates that “quantum software” is advancing at a pace parallel to hardware. Google applied Quantum Echoes to a proof of concept experiment for Nuclear Magnetic Resonance. This technique acts as a “molecular microscope”, a powerful tool that will help design drugs or, for example, establish the molecular structure of new polymers. a marathon. This new milestone demonstrates the progress that this technology has made in recent years, but Google is not alone here. Microsoft or IBM have also made notable advances in recent years, and of course there are numerous startups both in the US like in china who work in this area.

Russia has found a key advantage to multiply the range of its most lethal weapon in Ukraine: Chinese factories

by

Last July Reuters was made with some documents that proved the scope of the help from Beijing to Moscow with the war in Ukraine as a backdrop. The proliferation of Russian drones was possible thanks to a system labeling called “industrial refrigeration units” during transportation, one that allowed sanctions imposed by the West to be bypassed through fictitious companies. Now we know something else: that there are entire factories dedicated to collaboration. The invisible industrial alliance. The war in Ukraine has entered a new phase in which Russia’s technological advantage on the battlefield increasingly depends on a network of factories and chinese suppliers. Although Beijing proclaims neutrality, the official customs data show a spectacular increase in exports of critical components (especially fiber optic cables and batteries lithium-ion) that have allowed Moscow to mass-build the wired drones that are transforming the balance of power on the front. These aircraft, operated through ultra-fine glass threads that unwind in flight up to more than twenty kilometers, They are almost immune to electronic warfare and have managed to breach Ukrainian defenses with an efficiency reminiscent of a silent industrial evolution. The Chinese quantitative leap. How much? counted the Washington Post that between May and August, Chinese exports of fiber optic cables to Russia multiplied tenfold, reaching 528,000 kilometers per month, while shipments of lithium-ion batteries climbed to $54 million. In contrast, Ukraine barely received a few tens of km of cable and a testimonial volume of batteries. For analysts, this asymmetry it is not coincidental: China has restricted the transfer of technologies to kyiv and its allies, but has opened the floodgates of the flow towards Moscowtransforming what were simple commercial components into decisive pieces of the Russian war machine. The combination of low cost, high production capacity and speed in developing prototypes makes Chinese factories a material extension of the Kremlin’s war effort, a “precision rearguard” capable of sustaining the offensive even under Western sanctions. The weapon against electronic chaos. we have been counting. Faced with Ukrainian dominance in FPV drones, Russia has found fiber optic models a devastating tool. As they do not depend on radio frequencies, these devices are impossible to block through interference, and their wiring guarantees total control even in environments saturated with electronic warfare. Moscow uses them to destroy logistics lines, command centers and jamming equipment before launching offensives terrestrial. Its scope (coinciding with the advances measured “by sections of cable”) illustrates how this technology defines the very geometry of the front. Since the Ukrainian withdrawal in the Kursk region, wired drones have been the protagonists of precision attacks, such as the registered in Kramatorsk on October 5, cementing a pattern of warfare in which electronic resistance has become useless. The new factories of conflict. After the withdrawal of the giant DJI of the Russian market in 2022, a constellation of minor Chinese manufacturers has taken up its space. Companies like Shenzhen Huaxin Energy either Nasmin Technologyofficially dedicated to civil products, have become major suppliers of batteries and motors for Russian assemblers. The signature Rustakt LLCone of the largest in the Russian military sector, imported from China more than 577 million dollars in pieces between July 2023 and December of the same year, a volume that reveals the scale of covert industrial support. In turn, Russian manufacturers as ASFPV or Stribog exhibit on their websites production lines located in Chinese territorywith personnel, machinery and labels in Mandarin, manufacturing ultralight coils 0.28 mm and 20 km range designed by Chinese engineers. It is a transnational industrial network that no contracts needed formal military to nourish the Russian war effort: the flow of trade is its camouflage. The dilemma of the West. We have also been counting. Despite the sanctions imposed by the United States and the European Union, the majority of these shipments are protected by the ambiguity of the products “dual use”whose civil application allows controls to be avoided. For NATO, China has become a “decisive facilitator” of Putin’s war, Brussels accuses it of selectively applying its own export rules and to tolerate traffic of components that supports the Russian military industry. Beijing, meanwhile, continues to proclaim its neutrality, while its industrial system benefits economically from the prolongation of the conflict. Its strategy is subtle but effective: it does not supply weapons, but the infrastructure that makes them possible. A strategic advantage. Taken together, the convergence between Russian ingenuity and Chinese manufacturing capacity has created a war ecosystem that combines improvisation with industrial efficiency. The fiber drones optics symbolize that symbiosis: cheap, adaptable and difficult to counter. By providing Russia with technological independence from sanctions and tactical superiority on the battlefield, China not only strengthens its strategic partner, but also redefines global balance of power around a new form of hybrid warfare, where factories and cables count as much as missiles. The result is a cumulative advantage that, in the long term, threatens to turn the Ukrainian front into a manufactured warfare laboratorysupported not so much by soldiers, but by production lines on the other side of the world.

While the world desperately seeks rare earth, China has an overwhelming advantage: it’s called Wem

by

It seems clear that it has begun A race On the planet: the search for Rare earths and the essential critical minerals for many of the sectors that mark the geopolitical agenda. The problem for 99.9% of nations is the same: when they seem to have reached a deposit there are already A Chinese flag. What is not usually explained so much is how Beijing does. The miliar origin. Deep in the mountains of center of China extends A monumental installation that transforms both the landscape and the global competition for strategic resources. It is a gigantic antenna of 500 kilowatts, with lines that are deployed over 80 and 120 kilometers, originally conceived to maintain communication with underwater underwater. This electromagnetic colossus, whose extension exceeds in five times the New York surfacehas been converted into a decisive instrument for the exploration of critical minerals, projecting signals capable of penetrating kilometers in the earth’s crust and revealing deposits that previously remained out of human reach. What began as a military project has become a Scientific and Technological Weapon which gives Beijing a remarkable advantage in the race for the resources that will define the future of energy and industry. Electromagnetic exploration. A study of the China Geological Survey (CGS), published in the Geophysical & Geochemical Exploration magazine, has detailed how the country has managed to monopolize Electromagnetic systems of ultra-high power. All platforms that exceed 100 kW are in Chinese territory, while the most powerful tool in the United States barely reaches 30 kW. The difference is not trivial: this technological leap has allowed Chinese geologists to discover in recent years sites of historical magnitude, such as the Greater gold deposit of the world, reserves Lithium ultra-extends and uranium veins in depths Never achieved. The research led by Chen Hui and his team affirms That these innovations consolidate China’s world position in electromagnetic exploration theory and technology, placing it far ahead of any western competitor. The challenge. As the superficial deposits of copper, lithium, cobalt and rare earths are exhausted, the exploration has moved to what geologists call The “Second Mineral Space”: An underground strip that extends between 500 and 2,000 meters deep. In this environment, the signs issued by mineral bodies are extremely weak and are usually buried under the cultural noise generated by electricity lines, urban infrastructure and extractive operations. The Chinese response has been to redefine the scale of prospecting: multiply the transmission power by above 100 kWflooding the subsoil with signs capable of crossing interference and reaching depths of up to 3,000 meters with unprecedented clarity. Advances in the subsoil cartography. The jump is not limited to power. While conventional techniques relied on two -dimensional models not suitable for complex structures, Chinese systems use Sensors distributed networks and multidirectional field sources that allow a real three -dimensional image of the subsoil. In the Jiama copper mine, in the Tibet, a controlled audio-magnetothelúrica tensorial study (CSAMT) reached unpublished resolutions at more than 3,000 meters, subsequently confirmed with drilling nuclei. These results They far exceeded to the Magnetotheluric of Natural Source, usually ineffective in saturated noise environments. The methods. One of the most prominent advances is the Electromagnetic method wide field, developed by Professor He Jishan, which allows you to obtain reliable data even in the so -called “nearby field zone”, where the records were not very useful. At the same time, the time-frequency electromagnetic systems are expanding the available information by measuring not only the resistance of the materials, but also its polarization and permeabilityessential parameters to distinguish between different types of deposits. The Wem project. And so we reach the clearest symbol of this ambition: The Wem project (Wireless Electromagnetic Method), whose colossal structure crosses China’s heart with two antenna lines arranged almost at right angles. This system, which began as a naval communication tool, has become the First electromagnetic transmitter of continental scale used in the prospecting of resources. In a national test carried out in 2023its signs were detected from Tibet to Interior Mongolia and Guangdong, more than 2,000 kilometers away. In the area of ​​Xiong’an there were magnetic fields up to seven times higher than the natural background noise, an unequivocal demonstration of the system’s capacity to impose itself on the most complex interference. Strategic advantage. In other words, with these Beijing technologies It is placed at the head of the struggle for the essential mineral resources for the energy transition and the green technologies: lithium for batteries, cobalt for high resistance alloys and rare earths essential in modern electronics. In contrast, most Western countries lack comparable systems and, except Russia, almost none use ultra-high power instruments in terrestrial prospecting. Even the most powerful teams manufactured in the West have been designed at China, which underlines the existing technological dependence. A new geopolitical board. China’s ability to identify deep deposits quickly Not only is it a scientific advantage, but also strategic. Control over technology and data places Beijing in a position to mark the rhythm of the discovery of resources in the coming decades. If you want, in a context where the energy transition redefines the global value chains, who controls access to lithium, cobalt and rare earth will control much of the industrial future. With the deployment of Giant antennas and electromagnetic systems Of unpublished power, China is making it clear that it does not intend to participate in the race: its goal is to win it.

With the bird between Galicia and Madrid cut by the fires, someone has taken advantage of it to earn money: the airlines

by

Spain burns. And Zamora, León and Ourense are taking the worst part. The number of spotlights and their virulence is such that it has forced to cut the circulation of high speed between Zamora and Galicia. Some roads are cut. Renfe does not offer a solution. And, in the background, the airlines win. Cut. Rail traffic between Zamora and Galicia is cut. Renfe has confirmed today that trains will not circulate again in what remains during the day and there is not a single glimpse of hope that The situation can be reversed in the short term. In the Last DGT updatethere are six lonely cut roads and two in Zamora. None of them correspond to the great highways such as A-6, A-66 or A-52 that structure the northwest of the country. Despite this, Renfe does not offer a bus alternative to those who cover Madrid-Zamora or Zamora-Madrid by train, only open section in the high-speed Galician corridor. What can the traveler do? Those who had a high speed ticket in the Galician corridor have three options. The first is evident, do only the section between Madrid and Zamora and then take a bus or a car to Galicia. The second is to perform the entire road tour. The fastest road is obviously the plane. Prohibitive prices. But those who are obliged to travel will find exorbitant prices to cover the distance that Madrid separates from Galicia. Especially if the traveler travels from Galician lands to Madrid.

To this movement we must add the Partial output of Ryanair This same year of Galician airports, offering 61% less trips in Vigo and 28% less in Santiago de Compostela.

What are constellations and why scientists are still taking advantage of this millenary tradition

by

The human being has from prehistory looking at the night sky to guide himself, either looking for the north to establish our course, or in order to know what is the ideal time for the planting of a crop. We have also often sought in the stars the esoteric and the divine. The stars have helped us to locate in space and time. And to guide ourselves in the tangle of bright dots that populate the night sky we have often resorted to an old “trick”: the constellations. What is a constellation The constellations are Star groups that are close to each other in the celestial vault. Not so in the universe, the stars that share a constellation Thousands of light years can be located on each other, it is only their position related to the field of vision that we have on earth. The constellations were created when our ancestors assigned a form to these groups: whether the shape of a person or deity (as in the constellations of Andromeda, Orion or Virgo), an animal (the major and minor bears, or the constellations of Aries and of Taurus), an object (such as Erídano, the oven or the clock) or other mythological being (such as the hydra or draco). The constellations change depending on the time of the year and the region in which we place ourselves: there are constellations that are only visible in winter, others in summer; Some can only be seen from the southern hemisphere and others from the north. All this due to the relative position of the earth regarding the “backdrop” of the universe and the sun, which blinds our vision of the stars during the day. The constellations are therefore groups of stars in our sky and the way in which their position is distributed. Groups that were probably used Since ancient time as a mnemonic trick to distinguish stars and, with them, identify times of the year or to use as a compass with which to guide us. How many constellations are there? To use constellations as a systematic tool, scientists have developed an “official” constellation list. Thanks to this we can list a specific amount of constellations. How many? 88 in total. And who says it? The institution in charge of designating constellations is the International Astronomical Union (UAI), responsible for the nomenclature of many other elements in space and in the celestial vault. The delimitation of the celestial borders depending on the constellations as we know it today was approved by the UAI almost a century ago, in 1930. It was then that the proposal of the Belgian astronomer was published Eugène Joseph Delporteapproved two years before by the General Assembly of the agency. What is the origin of the constellations These constellations came to us through ancient Greece, but we know that they did not originate there but had a even older originperhaps in the Babylonians or in other civilizations of the surroundings of the “fertile growing”. We also know that this type of cartographies arose In various civilizations Far from each other, from South America to China. These constellations came to us through ancient Greece, but we know that they did not originate there but that they had an even older origin, perhaps in the Babylonians or in other civilizations of the surroundings of the “growing fertile” lifting. We also know that this type of cartographies arose in various civilizations distant from each other, From South America to China. The origin of the “modern constellations” is in two points. The first, the fact that the era of exploration led Europeans to have to orient themselves in the southern hemisphere, where some of the constellations are not visible, but where the reference of these can also be useful. How science uses constellations Although constellations are based on tradition and not on the use of the scientific method to order the stars, science makes use of them in certain contexts. Precisely this need to “cover holes” It is due to the use made by constellations today and is to serve as a reference for the Observation of objects and phenomena astronomical. The celestial vault can be divided into latitudes and lengths, with its degrees, minutes and seconds, in the same way we do with the surface of the globe. This way of dividing the sky can be useful, but it is also not very intuitive if we do not have other references. On Earth we have cities, countries and continents; In the sky, constellations can help us intuitively locate a specific point in the vastness of the night sky. Difference between constellations and galaxies Are not the galaxies of stars also? The constellations resemble galaxies in the fact that both terms refer to groups of stars, but beyond this fact, the differences are non -existent. While constellations represent groups of stars that are in proximity from our perspective, galaxies are formed by groups of stars that are found gravitationally anchored each other. Galaxies are also composed of many other elements linked in the same way, from dust and gas clouds even black holesthrough planets and asteroids. The terminolgia can be confusing by the way we have to name some and other elements. For example, if we talk about Andromeda we can be referring to both a constellation and The homonymous galaxy. This coincidence is precisely because the galaxy was baptized with the name of the celestial region where you have to look to find it: the Andromeda constellation.
