Quantum computers are going to overthrow classical cryptography sooner than expected

by

Just two weeks ago a group of researchers from the California Institute of Technology (Caltech), the University of California at Berkeley and the emerging company Oratomic published a scientific article preliminary in which they explore the capabilities of quantum computers of neutral atoms. These machines are an alternative to quantum computers with superconducting qubits and ion traps, and are still in an experimental phase. However, these scientists have estimated that Shor’s algorithm can be implemented using a quantum computer equipped with between 10,000 and 20,000 qubits of neutral atoms. In fact, in their article they even propose a design with which in theory it would be possible break bitcoin encryption in a few days using 26,000 qubits of neutral atoms. In any case, these researchers are not the only ones who in recent weeks have alerted us to the ability to violate classical cryptography that quantum computers will acquire in a relatively short period of time. At the end of last March, Google’s quantum artificial intelligence group published a study in which he demonstrates that the elliptic curve encryption used by Bitcoin or Ethereum, among other cryptocurrencies, can be overthrown using far fewer resources than initially estimated. According to these researchers, a quantum computer with less than half a million physical qubits will be able to decipher the algorithms used by current cryptocurrencies in a few minutes. In short, the scientific community has agreed that classical encryption technologies will be vulnerable before the arrival of large-scale quantum hardware. The first steps to protect ourselves have already been taken Quantum computing experts have known for several years that quantum computers they will end classical cryptography. That moment came in May 2024. A team of researchers from the University of Shanghai (China) led by Professor Wang Chao used a D-Wave quantum computer to successfully break SPN encryption (Substitution-Permutation Network), which is a cryptographic algorithm used to encrypt information. This encryption is the cornerstone of, for example, the AES standard (Advanced Encryption Standard), which is used a lot. These scientists published the results of their research in an interesting article titled “Quantum Processing-Based Public Key Cryptographic Attack Algorithm with the D-Wave Advantage.” However, this is not all. And in mid-May 2025, several Google researchers posted an entry in the blog dedicated to the security of this American company in which they maintain a crucial premise: an RSA integer (Rivest–Shamir–Adleman) 2,048 bits can be factored in less than a week with a quantum computer of less than a million qubits. A 2,048-bit RSA integer can be factored in less than a week with a quantum computer of less than a million qubits Bitcoin, Ethereum, Solana and the other modern cryptocurrencies use a cryptography technique known as elliptic curve that is more robust, efficient and difficult to break than RSA, but its mathematical foundations are similar to those of the latter encryption algorithm. In fact, according to the Google scientists who authored the article I mentioned above, if future quantum computers will have a harder time breaking RSA encryption than initially expected, elliptic curve cryptography will also fall relatively easily. So far we have talked about cryptocurrencies, but it is crucial that we do not overlook that encryption technologies play a fundamental role in our daily lives. In fact, WhatsApp and Telegram use them to encrypt our messages; banks turn to them to protect our transactions and every time we buy something on the internet it is encryption that is responsible for protecting our credit card information. These are just some of the applications of this technology. The threat of quantum computers to encryption technologies is very real, but we have no reason to panic because many researchers have been working on the solution to this challenge for several years. In fact, most of the theoretical work has already been done. In 2024, the US National Institute of Standards and Technology (NIST) published an initial set of standards that includes a post-quantum key exchange mechanism and several post-quantum digital signature schemes. The work that has already been done invites us to foresee that the moment relevant quantum computers appear from a cryptographic point of view, the technologies that will be able to protect our information will already be ready.

Google sets a date for “Q-Day”, when quantum computing will be able to break current cryptography sooner than expected

by

The arrival of the quantum computing brings us closer to an exciting horizon. It is a paradigm shift because, if classical computing is based on bits of 0 and 1, quantum computing uses qubits that can be in both states at the same time. Translation: if classical computing does operations one at a time, quantum computing does many at the same time. This opens up an ocean of possibilities, and will also allow any current encryption system to be broken. in a matter of seconds. Google has been around for a decade getting readyand has set a date for his arrival. 2029. PQC. It stands for post-quantum cryptography. It is a set of encryption algorithms designed to resist attacks by quantum computers and allow data that must be encrypted such as keys and digital signatures to remain so in the long term. Those complex mathematical algorithms designed to resist quantum attacks are designed to be implemented on classical computers. That is, it is not the hardware that is updated, but rather the security. Quantum cryptography is another approach, but also more experimental. It is the one that will use the full potential of quantum computing to achieve theoretically unbreakable security. The one that interests us at the moment is post-quantum, and it makes perfect sense because classical and the quantum They will coexist, and what is needed is to update encryption systems so that companies continue to have classic computers, but with security that resists quantum attacks. Q-Day. Companies have been preparing for this for a long time and, as we say, Google is one of them. Carry from 2016 investing in that post-quantum cryptography, migrating some key exchange systems for internal traffic to the post-quantum standard. A while ago they claimed that key exchange within Google services is now resistant to quantum computing by default. Proton also is in it. So as not to leave it there as a pending task that is never finished, they finish to mark a self-imposed deadline to complete the transition. By 2029 they will have to complete this migration of their security to PQC systems. In fact, on their blog, they have announced that Android 17 will integrate an algorithm that will provide quantum-resistant signatures to protect the integrity of boot software. It is a way of saying “hey, we are already preparing,” but basically what there is is a commitment to that security for a time that is near. And it won’t just be the boot system: applications will be able to generate and verify post-quantum signatures within the devices’ secure hardware, and Google Play itself will also begin generating secure keys for applications that choose to participate in the program during the launch cycle of the new system. The industry prepares. Aside from the announcement, the company urged the rest of the technology industry and governments to step up to accelerate the adoption of these more resistant encryption systems. And, although Google has been saying “the wolf is coming” for several years, they are not the only ones. Microsoft wants to start migrating its systems by 2029, culminating in 2033. US federal agencies also want do it for the 2030-2035 window and the European Commission has urged member states to make critical infrastructure resilient by the end of 2030. With this movement, Google has set a date that seems ambitious and is a declaration of intentions. “It is our responsibility to set an example and share an ambitious schedule,” says Google. It is also evident that as a digital infrastructure provider, offering a post-quantum security system before anyone else gives you a competitive advantage because if someone doesn’t arrive on time, they could always buy your services. Companies like Telefónica are also working on it, but when we talk to them They did not give us an indicative date. What they did comment is that they are beginning to see that there are parts of the industry that are becoming interested in their post-quantum cryptography services. Don’t panic. that the arrival of quantum computing represents a headache for everything that is encrypted (blockchain and cryptocurrencies, banking data and transactions and even messaging apps) does not mean that we have to panic. A few months ago, Keith Martin, professor in the Information Security Group at the University of London, commented that, although the threat is realresearchers have been working for years and most of the theoretical work is done. When cryptographically relevant quantum computers appear, the protection technologies will already be ready and we will not have to worry about anything. In fact, at the user level… we can do little. We are not going to be the ones who have a quantum computer at home to be able to encrypt our information. Basically, as I said a few lines ago, it is Google saying “get ready because this is going to come and, as an industry, we have to prepare.” And they have already set a date.

China has always dreamed of a “Polar Silk Road” so that its ships reach Europe sooner. It is already a reality

by

Monday was an important day in Felixstoweone of the largest container ports in the United Kingdom. Towards the end of the afternoon, their workers saw the silhouette of the Istanbul Bridgea container ship loaded with lithium batteries and parts for the photovoltaic industry. In itself, the appearance of the Istambul did not represent anything new, the curious thing was where it came from or (more precisely) where it arrived: with its arrival at the docks of Felixstowe the ship completed a historic voyage of 20 days through the Arctic Ocean. Its journey to the British coast has allowed China to take a key step in achieving one of his big dreams: a ‘Polar Silk Road’ with Europe. What has happened? That China has achieved a milestone in maritime trade. Perhaps more symbolic than decisive, but still important. Late on Monday the container ship Istanbul Bridge arrived in the United Kingdom after a trip that had started 20 days before in Ningbo-Zhoushana very important port hub on the coast of the East China Sea. So far nothing strange. The key is that the Istanbul Bridge did not reach Felixtowe in the usual way, after detouring south to cross the Suez Canal and advance through the Mediterranean and the Atlantic towards Europe. No. He did it on the voyage that took the ship through northern waters, through the icy Arctic Ocean and the North Sea. AND that is relevant. Why is it important? The Istanbul, a ship with capacity for 4900 containers standard (TEU), 299 meters in length and flag of liberia (although in reality it has operated bound to the Chinese Sea Legend and Haijie Shipping) it is not the first ship that sails along what is known as the Northern Sea Route, but its voyage has had a special meaning. As remember CNNthe first ships loaded with containers began sailing through the Arctic more than a decade ago, but it is normal for them to do so on special and specific trips. The Istanbul Bridge has another approach. Since his departure from Ningbo-Zhoushan has been presented as proof that the northern route can be used as “a traditional line service”, with commercial stops. “It’s something we haven’t seen in the Arctic until now,” recognize Malte Humper, from the Arctic Institute. The ship took 20 days to complete its journey between China and the United Kingdom loaded with about 4,000 containers and its objective, beyond Felixstowe, is to unload merchandise in other ports in Germany, Poland and the Netherlands. As required According to the Chinese agency Xinhua, the ship was mainly transporting lithium-ion batteries and parts for the photovoltaic industry, goods that are sensitive to heat and in which delivery times are a strategic factor. And why this interest? Because the ultimate objective is not to stop at the feat of the Istanbul Bridge, but to promote the trade route known as “China-Europe Arctic Express”, an itinerary that connects first-class ports such as Ningbo, Shanghai, Qingdao, Dalian, Felixtowe, Rotterdam, Hamburg and Ganks. In fact even Ningbo Customs has referred to the expedition as “the official opening of the first China-Europe Arctic Express container route.” State broadcaster CCTV it is very clear in fact when referring to the voyage of the ship. In his opinion, “it represents the maiden voyage of the first Arctic express container route between China and Europe and demonstrates the commercial viability of the Northwest Passage.” High North News precise that at least for now the route will be seasonal and the shipping company Haijie Shipping plans a single sailing in 2025 (the navigation window is still limited and lasts a few months), but the company seems to have noted the interest of manufacturers and shipping platforms. e-commerce. Is it that interesting? Yes. And it is because its main advantage is speed. The container ship has taken only 20 days to complete its journey, two more than those initially planned. The reason for the delay was a storm passing through the Norwegian Sea that forced him to slow down. Despite this, it represents a notable time saving on China-Europe trips when compared to other much more established alternatives in the sector. As remember Xinhuathe China-Europe Express Railway requires 25 days of travel, transporting goods through the Suez Canal route requires 40 and doing so through the Cape of Good Hope 50. “Trade between China and the European Union has remained strong despite the volatility of the global trade landscape and having a third route, in addition to the traditional shipping corridors and the China-Europe rail service, will bring stability and inject new vitality into bilateral trade,” highlights Cui Hongjianfrom the China Institute of International Studies in Global Times. The Asian newspaper (linked to the Government) does not leave much room for doubt in its report on the Istanbul Bridge: “It represents an emerging international shipping artery of great value to optimize the global supply chain.” Why right now? For several reasons. The main one, because the Arctic of 2025 is not the same as the one of three, four or five decades ago. And it probably won’t be the same in the future either. As climate change progresses and ice fractures and melts, the Arctic is gaining interest as a navigable space. Nikkei assures that its loss has caused the number of ships accessing Arctic waters to have increased by nearly 37% while the total distance traveled has doubled. All in the last 10 years, according to the data managed by WWF. More factors come into play, the reinforced interest that the European market has gained for China in the midst of a tariff war with the United States or the challenges that maritime traffic has encountered in other latitudes, such as the Suez Canala key logistics point that has demonstrated its vulnerability. The northern route also offers extra advantages, such as considerable time savings for shipments destined for Christmas shopping in Europe and low temperatures. Are they all advantages? At all. Perhaps the Arctic has changed, … Read more

Sooner or later China will be the world chips leader

At the moment nothing indicates that Donald Trump’s arrival at the White House will relax the tension held by the US and China. The strategy of the new US government on many fronts is very different from the one defended by the administration of Joe Biden (The Ukraine War is one of them), but in what It refers to China a priori nothing changes. And does not do so because the nation led by Xi Jinping is the only one that has the ability to play world supremacy to the USA. In fact, the government led by Joe Biden openly recognized the document that collects its National Security Strategy October 2022 that China has the necessary capacity and resources to dispute the US Its world leadership position. A good part of the sanctions deployed by the US government and its allies seeks to slow down the development of the Chinese semiconductor industry due to the deep impact that it has on its scientific, economic and military capacity. But China bids increasingly. China leads chips research with overwhelming roundness Currently the biggest challenge facing the China semiconductor industry is the set -up equipment of extreme ultraviolet lithography (UVE) similar to those produced by the Dutch company ASML. The US and Netherlands sanctions prevent this company from selling them to their Chinese customers, and these equipment are necessary to produce on a large scale and with a competitive cost integrated avant -garde circuits. In 2023 the Chinese government approved a 41,000 million dollar game for lithography equipment manufacturers In this situation, the only way China can follow is to dedicate a lot of resources to research with the purpose of matching, or even exceeding the level of development they have achieved in the field of Taiwan semiconductors, USA, South Korea or Japan. And is doing it. At the beginning of September 2023 the Chinese government approved a departure of no less than 41,000 million dollars Destined precisely to the companies that produce the equipment involved in the manufacture of integrated circuits. The achievements are already arriving, and are notable. SMIC and HUAWEI have opted, at least for now, for refining their lithographic processes and optimizing UVP lithography machines (deep ultraviolet) manufactured by ASML that they already have in their possession. Other companies, however, have chosen to develop their integration technologies relying on the new teams that Naura Technology, Amec (Advanced Micro-Fabrication Equipment Inc. China) or Piotech Inc. have taken to point. This is the path that You are following Yangtze Memory Technologies Co. (YMTC), the largest memory chips manufacturer in China. However, China’s authentic strength is its ability to develop avant -garde research. He Emerging Technological Observatory (ETO), which is an international organization specialized in the analysis of the adoption of emerging technologies globally, points out that Between 2018 and 2023 475,000 articles were published dedicated to the design and manufacture of chips throughout the planet. 34% was produced by Chinese institutions, while Europe is formed with 18% of those articles and the US with an even more modest 15%. In addition, again according to Eto, Chinese articles are among the most mentioned, which supports their quality. This trend draws a future on the horizon in which China’s weight in the semiconductor industry will be increasing.

Netflix is ​​not worried that users cancel the subscription. The data reflect that, sooner or later, most return

How is it possible that content platforms on demand They rise in price year and year also if every time users cancel (or say they cancel) their subscription? It’s curious. Normally, in another context, it would be that price increases and foreseeable cancellations affected companies, but Netflix does not seem that it matters. Rather. Context. Despite price increases and the wave of cancellations that comments on social networks usually imply, the reality is that Netflix’s benefit It was 10,247 million dollars In the fourth quarter of 2024, 16% more than the same quarter of the previous year and the best result since 2021. Was the users canceling their mass subscriptions? If we understand “mass cancel” as in the United States only 19 million subscribers arrive in the fourth quarter of 2024 when Netflix expected 9.8 million, then yes. Comes back. According to data from the Analytical analysis company to which it has had access Business Insiderthe reality is as follows: price increases cause cancellations, yes, but users do not take long to return. The case of Netflix is ​​also curious because this “repentance” is greater than on the rest of the platforms. The data. According to Antenna, 50% of users who cancel their subscription subscribe at six months. If we expand the time range until the year, the percentage rises to 61% of users. In other words, six out of ten cancellations recover after the year. In the case of having canceled a price increase, the return will be with updated prices, ergo paying more and compensating in some way the cancellations not recovered. Moreover, it is most likely that user who returns to opt for a cheaper plan, but with advertising. 55% of the new highs They choose that modality, in fact. The data reflects that the Netflix subscriber recovery rate is much higher than that of its competitors Netflix vs the world. The consultant’s data shows that Netflix’s recovery rate is much higher than the average of the rest of the platforms. While at six months Netflix recovers 50% of users, the rest of the platforms barely recover 34%. In the case of Netflix it is also striking that two out of ten cancellations recover in just one month. There is a roof. Netflix has not stopped innovating in its programming, moving from series and films to also offer sports and live events. 300 million subscribers give good faith that this has worked, but everything has a limit. Netflix seems aware that 1) continuing to grow will be complicated and 2) “As we continue to invest in programming and offer more value to our partners, we will occasionally ask them to pay a little more to be able to reinvest and continue improving Netflix.” That is to say, that prices will continue to rise. Netflix knows that continuing subscribers will not be easy and maybe that explains that from now Don’t give that figure. We will know numbers of audiences, view, benefits, growth, etc., but not how many subscribers do Netflix have. Most likely, we will not see that data again until the 400 or 500 million are reached, very publicitable figures and from which the platform can breastfeed.

You are going to receive One UI 7 sooner than you expected

by

Today is the big day for Samsung, the moment that all technology and smartphone enthusiasts have been waiting for: the Galaxy Unpacked 2025, with the presentation of the new Galaxy S25the brand’s new leading mobile phones. However, these will not be the only protagonists of the evening, and Samsung is preparing some surprise that has not yet been leaked. The good news is that you won’t need to buy a new product to enjoy some of these surprises. And Galaxy S24 users are finally going to receive the update to Android 15, with the upcoming release of One UI 7 for all devices. Samsung itself has confirmed this, through a moderator in its official forums, as shared Sammy Fans. One UI 7 is the new version of Samsung’s customization layer, now based on Android 15. Although Samsung was one of the first to make the jump to Android 14 two years ago, with this version it has taken a little longer; the consolation is that One UI 7 will bring a good amount of new features and many of them related to Galaxy AI and its Gemini-based AI functions. Now, Samsung has confirmed that One UI 7 will be available to all Galaxy S24 users at the same time. This is an important detail, because it means that Spanish users will not have to wait for the update, as has happened in past versions. In other words, it will be a global launch that will be available on all models in the Galaxy S24 range at the same time. It is somewhat surprising, considering that the One UI 7 beta has only been available in seven countries, including Spain; Only users from China, Germany, India, Poland, South Korea, the United Kingdom and the United States have been able to participate in the open beta, which It started last December and has already resulted in three major updates so far. Samsung The Free Android In fact, now the question is whether a fourth beta version of One UI 7 will arrive, as users are already asking for, or if Samsung will directly launch the final version of the layer soon. What does seem clear is that One UI 7 will debut first on the new Galaxy S25 that are presented today, which will come with the new version of Android from the factory and without the need to update. Taking into account today’s announcement, it is very possible that One UI 7 will be released for the Galaxy S24 at the same time, or around the same time, as the launch of the Galaxy S25. Therefore, we will not have to wait long to enjoy its new features on our mobile phones.
