The first dual core and 200 qubits on the planet is now ready

by

The pulse between the US and China in the field of technology goes beyond semiconductors and the artificial intelligence (AI). The US leads the industry quantum computersand, although probably not all the achievements that Chinese companies and research centers have achieved have transcended, those that we know of reflect that China is also a power in quantum computing. In fact, these two countries have achieved notable milestones over the past few years. The quantum supremacy is one of those that share, but if we stick to quantum telecommunications China is intractable. In addition, the country led by Xi Jinping is one step away from having indigenous superconducting quantum computers. In recent years, Chinese companies and research centers have been forced to buy high-density microwave connectivity modules abroad, mainly in Japan. This dependency is about to come to an end, if it has not already done so. Be that as it may, the latest milestone for this Asian country has been signed by CAS Cold Atom Technology, a Chinese quantum technology company based in Wuhan, the capital of Hubei province. And it has presented the world’s first quantum computer with neutral atoms and double core: the Hanyuan-2. We have known for a long time that China is very advanced in superconducting qubits, but now we also know that it is a competitive country in qubits of neutral atoms. Hanyuan-2 is a unique machine Neutral atom quantum computers are an alternative to quantum machines with superconducting qubits and ion traps, and are still in an experimental phase. Those responsible for the design of Hanyuan-2 have confirmed that this device incorporates two independent and complete arrays of qubits of neutral atoms. It integrates 100 atoms of rubidium-85 and another 100 of rubidium-87 to build a dual-core system that implements a total of 200 qubits. Each logical qubit is abstractly built on top of several physical or hardware qubits. Both matrices can work in parallel (hence this machine has 200 qubits) in order to increase its calculation capacity. However, and this is very interesting, one of them can operate as the main nucleus and the other can act as an auxiliary nucleus to build logical qubits. more stable and less sensitive to noise. An important note: logical qubits represent a way to overcome the difficulty involved in using hardware or physical qubits, which are extremely sensitive to noise, and therefore prone to making errors. Each logical qubit is abstractly built on several physical or hardware qubits, so that a single logical qubit encodes a single qubit of quantum information, but with redundancy. It is precisely this redundancy that allows us to detect and correct the errors that are present in physical qubits. Until very recently the number of hardware qubits needed to implement a single error-immune logical qubit made error correction infeasible in practice, but this limitation has been lifted thanks to the work of IBM and CAS Cold Atom Technology, among other companies. Although the quantum computer that you can see in the cover image of this article is the Hanyuan-1, its successor also has a conventional design. In fact, both look much more like a classical computer than a quantum machine with superconducting qubits or ion traps. What is truly striking about Hanyuan-2 is that does not need a cryogenic cooling environment to function. Instead, it uses a small laser cooling system with a total consumption of less than 7 kilowatts, which allows it to be installed in practically any space without extraordinary technical requirements.

The PS5 has always been a PC at its core. Some models can now run Linux and games

by

The PlayStation 5 It has never been a conventional computer, but it has never been as far from looking like one as we usually imagine. Under its casing there is an x86 architecture, an AMD Zen 2 CPU and a RDNA 2 GPUingredients very familiar to anyone who closely follows the world of PC. The difference, of course, has always been in control: Sony decides what is executed, how it is executed and how far the hardware can go. That is why what we have seen now is so striking: a PS5 Phat (launch model) booting Linux and behaving, with important nuances, like a desktop machine. The change. Everything arises with the publication of ps5-linux, a project by Andy Nguyenbetter known as TheFlow. We are not talking about a simple demonstration, but about a tool that really works with an image of Ubuntu 24.04. According to the description of the project itself on GitHubps5-linux uses an already patched vulnerability in the hypervisor. The promise is powerful, but as we will see below, it does not work on all consoles and also has several limitations. Not just any PS5 is worth it. So far, everything sounds great, but this doesn’t mean we can take the console in the living room and happily turn it into a Linux PC. First, because we are talking about a process designed for profiles with experience. And second, because compatibility is very limited. The method currently only works on PS5 Phat with firmwares 3.xx and 4.xx, specifically 3.00, 3.10, 3.20, 3.21, 4.00, 4.02, 4.03, 4.50 and 4.51. Additionally, versions 3.xx do not have M.2 support, while 4.xx does. The process is also not similar to inserting an installation pendrive and following the usual steps on a PC. According to Tom’s Hardwareps5-linux needs a separate tool, the umtx2 exploit, to achieve initial code execution, and then send the loader payload to the console. In the flow in question there is a fake DNS server and an HTTPS host on a local computer, which redirect the query for the PS5 manual to activate the exploit. When everything goes well, the console goes into sleep mode, the LED turns solid orange, and when you press the power button, Linux starts. Once inside Linux. The console now behaves like an x86 desktop with plenty of muscle to experiment with. The system can take advantage of the eight CPU cores, 16 threads in total, at 3.5 GHz, and a GPU at 2.23 GHz. It also maintains video and audio output via HDMI, with support for 4K at 60 Hz, and allows the use of all its USB ports. To install and run Linux you need a USB drive of at least 64 GB. What changes the perception of the project the most is not just seeing Ubuntu starting up, but imagining what it can be used for. TheFlow talks about Steam games and emulators running very smoothly, relying on the power left available when running Linux on these PSs. In X we can see running on the improved version of ‘GTA V‘, which helps show the loader’s potential before publication. It’s not all plug and play: The project has very specific limits that should be made clear before imagining a PS5 converted into a perfect substitute for a PC. One disappointing fact is that ps5-linux works as a soft mod, not as a permanent installation, so you have to repeat the process every time you want to enter Linux. Nguyen advises activating the ventilation profile when using boost modes, since the console was not designed for this type of use. The result is one of those modifications that explains very well how far a console can go when someone manages to take part of its hardware out of the intended lane. A PS5 Phat with old firmware can become a surprisingly capable Linux PC, but always within a very specific context. A console that is also a computer. The PS5, like any console, has always had computer ingredients. Now, the inevitable comparison is in the future Valve’s Steam Machinealthough there we talk about another philosophy: a console-PC designed from the beginning around SteamOS, but with the possibility of installing any compatible operating system to our liking.

A neutron core of the size of a bus

by

In the Ukraine War, nuclear It is not a purely arms issue. Among the most devastating scenarios that beat about the contest is the possibility of an error that leads to an unprecedented environmental disaster. We already knew that the Chernobil plant He had a hole And continue Without being able to repairbut the reach is much broader than the sadly famous plant. Under constant threat. The truth is that the Russian invasion of Ukraine has not only transformed the military map of Europe, but has put at risk an extensive network of nuclear facilities that were never designed to resist bombings. Although international attention has focused on Zaporiyia Centralthe largest in Europe and in Russian hands since 2022the country houses multiple reactors, research laboratories and spent fuel deposits that make up a delicate risk mosaic. Among them stands out Institute of Physics and Technology from Járkov, where is the known device as Neutron Sourcewhich contains several tens of kilos of enriched uranium capable of polluting vast areas if they were dispersed. Located just 14 kilometers from the front, the building has suffered More than 70 impacts Russian ammunition confirmed, which fears that Moscow’s goal is not accidental, but deliberate. Járkov, military white. The Institute, which in Soviet times contributed to the design of The first atomic bomb From Moscow, he agreed in 2010 withdrawing his uranium suitable for armament and sending it to Russia under pressure from the United States, in a non -proliferation effort. However, still custody materials of enormous danger, such as high radiation uranium contained in Neutron Source, built with US financing in exchange for that resignation. The installation combines a core of the size of a school bus with a particle accelerator about 30 meters, surrounded by metal shields, but the building that houses it It lacks protection in front of attacks. The bombings have left cracks, have dropped plaster of the walls and reached destroy a transformer In 2022, plunging the complex in blackout months and forcing scientists to improvise heating systems to avoid irreversible damage to fuel bars. Ukraine accuses Russia of echocideclaiming that a direct impact could release radiation on an area inhabited by 640,000 people. The nuclear installation of Neutron Source in Járkov on April 4 Chernobil’s spectrum. We have gone counting. Since the beginning of the invasion, the nuclear catastrophe scenarios have been present. In February 2025, A Russian drone pierced The steel structure covered by the reactor 4 of Chernobil, the most contaminated area of ​​the planet, breaking its hermetic seal, although without immediate leaks. In Zaporiyia, repeated attacks have put the cooling of the six reactorsespecially after destruction in 2023 on a dam that forced to depend on an emergency pond and two electric lines vulnerable to artillery. Each incident envives the fear of a radiological accident that, even without being of the Magnitude of 1986could disperse contaminating materials by large areas of Eastern Europe. The mere synchronization of certain attacks, such as Chernobil’s On the eve of the Munich Security Conference, it is played by kyiv and its allies as strategic messages of the Kremlin, which uses nuclear risk as a weapon of political intimidation. Collateral effects Plus: Not only Ukrainian facilities are in danger. At the end of August, remains of an intercepted Ukrainian drone They damaged a station Transformer in the immediate vicinity of the Kursk Central, in Russian territory, forcing to reduce its production. The episode illustrated how war turns civil nuclear infrastructures into collateral damage to a military confrontation in which drones, missiles and artillery operate increasingly closest to high -risk objectives. The experts Remember That no central or research laboratory in Ukraine was built to withstand direct impacts of modern ammunition, so the prolongation of the conflict multiplies the probabilities of an accident. Between resilience and constant threat. Had the New York Times In a wide report that, despite the daily danger, the Ukrainian scientists of the Járkov Institute They continue with projects of nuclear fusion and experiments with radioactive hydrogen, collecting data that they expect to present in international conferences. The paradox of continuing to investigate under bombing reflects both the resilience of the personnel and the fragility of a country that, in addition to resisting militarily, must guard materials whose release would have devastating consequences. In the words of one of the center engineers to the TimesRussian attacks seem to lack logic, but their repetition suggests a pressure strategy through radiological risk. Until now the catastrophe has been avoided fortune and technical contingenciesbut every day of war prolongs a pulse in which radiation could become involuntary or deliberate weapon, with effects that would overflow the borders of Ukraine.

A man paid $ 23 for a PC box at an auction. Discovered inside a 24 -core CPU and an RTX 3080 ti

by

Online auctions are full of unexpected opportunities, but few stories surprise as much as this. Imagine to enter a local second -hand platform with the idea of ​​getting a simple computer box. You don’t look for anything spectacular, Only a wide chassis for future projectssomething functional and cheap. You make a low, almost symbolic bid, and you don’t expect more than a basic article wrapped in cardboard. However, when picking it up, something does not fit: it weighs more than expected, it sounds different, and what seemed like a routine purchase becomes the beginning of an anecdote that sweeps Reddit. The story was known through Redditwhere the buyer published the discovery in R/PcMasterrace. According to images published by “Llamasusgame”, the box was not empty or contained old pieces, but a complete high -end computer. In his photos you can see a TRX40 aorus pro wifi motherboard with an AMD Ryzen Threadripper 3960X processor of 24 cores, accompanied by 256 GB of RAM and a graphics card NVIDIA GEFORCE RTX 3080 TI. Although the interior shows accumulated dust, the screenshot shared by the user indicates that the system works and recognizes all the hardware. When a cheap bid becomes treasure Operation data are available on the City online Auccans website, Where the lot remains published. It is number 123 and describes a box Fractal Design defines 7 xlwith price of $ 317.99. The final bid was $ 23.50 plus commission, according to the official file. The images associated with the ad barely showed the box inside a cardboard and a catalog photo, without giving clues of its real content. The contrast between the paid price and the real value of the components is striking. According to AMD and NVIDIA launch prices, only the Ryzen Threadripper 3960x processor It was originally sold for $ 1,399while the RTX 3080 TI exceeded $ 1,100 at its departure in 2022. Even with current depreciation, the complete set can reach several thousand dollars in the second -hand market, especially for the large amount of RAM. The announcement of capital City Online Auccans included clear warnings: all articles were sold “AS-IS, without guarantee, or possibility of return. He also insisted in what The bids should be based on the written description And not in the images, which could be filed. The collection was only face -to -face, without shipping option, and the regulations of the site establishes that any dispute must be resolved by arbitration in Ohio. The case raises an interesting issue: how far does the responsibility of a buyer get in such a situation? The user paid what the bid indicated and collected the article according to the standards, so no rule of the auction has breached. However, some commentators in Reddit wonder if he should have warned the company to correct what seems like a cataloging error. The capital policy online Auctions makes it clear that sales are definitive, but the ethical debate is still open: take advantage of luck or return the finding? The purchase of this PC box recalls that at online auctions there is always a risk and surprise component. In this case, the buyer obtained a high -level team For the price of a piece of chassis. Beyond the blow of luck, the story underlines the importance of reading the small print and reviewing the lots before any movement.

The earth’s core has a “escape.” And it’s gold

by

Our planet hides, thousands of kilometers under our feet, a mainly composed nucleus ironwith an important nickel concentration, and also with other intermingled elements. And among these latest elements, there is gold. Gold leak. Gold that, according to a recent study, It is leaked towards upper layers, in the direction of the surface and through the land mantle. A gold, in addition, that would have “escaped” of the earth’s core along with other precious metals. A tiny portion. Gold has been considered, since time immemorial, a precious metal and its “rarity” has been related to the value we have given to this element throughout the history of mankind. “Rareness”, quoted, since it is a contextual rarity. Gold is rare on the surface of our planet and in the most accessible areas of the cortex through mining. But this element is not universe in the universe, and it is not scarce on our planet Earth. So much that the “superficial” gold represents less than 0.001% of the total of this gold. Before and after. Someone might wonder why the gold of our planet has been distributed so capricious. It is because this cast has little or nothing capricious, and the reason is in the geological history of our own planet. When the land was still in the process of formation, about 4.5 billion years ago, gold and other metals ended up trapped in the planet’s core, due to gravity. Until now we believed that these metals would have been separated from the surface by the terrestrial mantle. The origin of surface gold, following this logic, could be for example in spacethanks to the infinity of meteorites that have reached the surface of our planet throughout its geological history. After the track of Ruthenium. This, we pointed out, not only with gold, also with other similar metals such as The Ruthenium (RU). The recent study was based precisely on this metal and a significant fact: that the Ruthenium typical of the Earth’s core presents a significant abundance of a concrete isotope, Ruthenium-10 (100ru), which distinguishes it from superficial root. The team responsible for the new study analyzed Ruthenium traces found in the volcanic rocks of the Hawaii archipelago to determine the presence of the 100ru isotope. Something that would have been impossible a few years ago, The team stands outit has now been possible thanks to new tools developed for analysis. Analysis that allowed linking the ruthenium found in these rocks with the earth’s core, which implies that this metal from the border region between the nucleus and the mantle would have risen until it sneaks into the volcanic magma. The details of the study were published In an article In the magazine Nature. Aboard the convective magma. Investigating what happens under the surface of the Earth has been over the years a task on the verge of the impossible. The propagation of the seismic waves revealed at the time very valuable information about the mantle and the nucleus, but increasingly precise measurement techniques have gone Opening new doors Over the years.
