Quantum encryption algorithms

Audio player loading… One of the potential encryption algorithms that was a serious candidate to be used in the quantum computing world has been defeated worryingly simply. The algorithm in question is called SIKE (Supersingular Isogeny Key Encapsulation), and made it through the encryption algorithm competition set up by the US Department of Commerce’s National Institute of Standards and Technology (NIST). In other words, it came quite close to becoming the standard encryption algorithm in a quantum computing world. However, it took researchers roughly an hour to break through it and steal encryption keys, using nothing but a single-core PC, and the power of mathematics. Attacking the math Even though SIKE did quite well during the government’s analysis, researchers with the Computer Security and Industrial Cryptography group (CSIS) at KU Leuven needed roughly an hour to obtain the encryption key. The report says that they did not try to find a flaw in … [Read more...] about The next generation of encryption may not be quite as secure as we’d hoped

Why it matters: In 2019, a paper leaked claiming physicists at Google used their quantum computer, Sycamore, to run a calculation that would overwhelm the world's most powerful supercomputer. Chinese scientists recently challenged that claim by successfully running the identical computation in a matter of hours using the computing power of today's GPUs. Their results prove a supercomputer using today's technology could likely beat Sycamore's previous record. Google's quantum computing researchers originally ran the complex calculation in 200 seconds (just over three minutes), a feat they claimed would have taken the fastest supercomputer upwards of 10,000 years. Based on this result, the team claimed they had reached a significant milestone known as quantum supremacy . Quantum supremacy is the point at which a quantum device can solve problems that otherwise cannot be solved by classical technology in any reasonable amount of time. Not everyone was a believer in Google's … [Read more...] about Scientists challenge Google’s quantum supremacy claims using 512 GPUs

Audio player loading… A team of scientists in China claim to have replicated the performance of Google’s Sycamore quantum computer using traditional hardware, thereby undermining the suggestion the company has achieved quantum supremacy. As reported by Science magazine, the scientists used a system comprised of 512 GPUs to complete the same calculation developed by Google to demonstrate it had passed the quantum supremacy milestone back in 2019. The endeavor was led by statistical physicist Pan Zhang, who said his team’s supercomputer performed the calculation 10 billion times faster than Google had thought possible. Quest for quantum supremacy Quantum supremacy (or quantum advantage) can be defined as the point at which quantum computers can outstrip the maximum potential performance of classical supercomputers in a particular discipline. Three years ago, Google announced it had achieved this feat with Sycamore, which it said took just 200 seconds … [Read more...] about Scientists say they’ve debunked Google’s quantum supremacy claims once and for all

Fast charging, a term which has become one of the core features in most modern smartphones and is also one of the sought-after features when buying a new smartphone. OnePlus has recently introduced its latest OnePlus 10T 5G smartphone globally. While it brings a slew of new features such as Qualcomm’s flagship chip, 16GB RAM and more. The 150W SuperVooC Endurance Edition charging and all the technologies associated with it caught our attention. For those who are not aware, fast charging speed comes at a cost and its own set of risks. For instance, charging a battery with that speed could deplete its life faster than imaginable. Also, there’s a risk of something going seriously wrong with it. However, OnePlus has managed to iron them out with its 150W SuperVooC Endurance Edition. , At the keynote OnePlus thoroughly explained what precautions and features they have included in the OnePlus 10T to make 150W fast charging a safe bet while ensuring that the battery would last … [Read more...] about oneplus: Explained: How OnePlus has made 150W fast charging safer ensuring battery health in the longer run

Even if you’ve never heard the term metadata, you’re definitely familiar with it — you probably use it every single day without even realizing it. Metadata is one of those essential things that manages to hide in plain sight. What Is Metadata? Metadata sounds like an intimidating term, but it isn’t — metadata is just data that describes other data. In many ways, metadata is a lot like a driver’s license or another kind of ID you’re familiar with. An official ID will usually have your date of birth, height, eye color, a picture, and other information about you. Metadata fulfills a similar role for digital files found on computers. Metadata will usually describe when a file or folder was created, when it was last modified , and other important attributes about it. RELATED: How to Easily View Recently Modified Files in Windows Different kinds of files will often have different metadata. Here are some specific examples of metadata that you might find attached to common … [Read more...] about What Is Metadata?
