D-Wave Systems is ramping up in the race to so-called quantum supremacy — the bid to become the first to successfully commercialize quantum computing.
Magnets and superconductors don’t normally get along, but a new study shows that ‘magic-angle’ graphene is capable of producing both superconductivity and ferromagnetism, which could be useful in quantum computing.
When two sheets of the carbon nanomaterial graphene are stacked together at a particular angle with respect to each other, it gives rise to some fascinating physics. For instance, when this so-called “magic-angle graphene” is cooled to near absolute zero 0, it suddenly becomes a superconductor, meaning it conducts electricity with zero resistance.
Now, a research team from Brown University has found a surprising new phenomenon that can arise in magic-angle graphene. In research published in the journal Science, the team showed that by inducing a phenomenon known as spin-orbit coupling, magic-angle graphene becomes a powerful ferromagnet.
A University of Melbourne-led team has perfected a technique for embedding single atoms in a silicon wafer one-by-one. Their technology offers the potential to make quantum computers using the same methods that have given us cheap and reliable conventional devices containing billions of transistors.
“We could ‘hear’ the electronic click as each atom dropped into one of 10,000 sites in our prototype device. Our vision is to use this technique to build a very, very large-scale quantum device,” says Professor David Jamieson of The University of Melbourne, lead author of the Advanced Materials paper describing the process.
His co-authors are from UNSW Sydney, Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Leibniz Institute of Surface Engineering (IOM), and RMIT Microscopy and Microanalysis Facility.
The bigger a quantum battery, the faster it charges.
Quantum batteries have the potential to store energy in a new class of compact, powerful devices that could boost our uptake of renewable energies and massively reduce our reliance on fossil fuels.
Now, an international group of scientists has taken an important step towards making these batteries a reality. According to a press statement from the University of Adelaide, the team has proved the crucial concept of superabsorption for the first time.
What is superabsorption? Through a series of lab tests, the team successfully proved the concept of superabsorption, a phenomenon of quantum mechanics with potentially vast implications in the fields of quantum computing and energy storage. Superabsorption, like many other quantum quirks, makes the seemingly impossible possible via subtle manipulation of molecules on the quantum scale.

All memory storage devices, from your brain to the RAM in your computer, store information by changing their physical qualities. Over 130 years ago, pioneering neuroscientist Santiago Ramón y Cajal first suggested that the brain stores information by rearranging the connections, or synapses, between neurons.
Since then, neuroscientists have attempted to understand the physical changes associated with memory formation. But visualizing and mapping synapses is challenging to do. For one, synapses are very small and tightly packed together. They’re roughly 10 billion times smaller than the smallest object a standard clinical MRI can visualize. Furthermore, there are approximately 1 billion synapses in the mouse brains researchers often use to study brain function, and they’re all the same opaque to translucent color as the tissue surrounding them.
Cloud computing and blockchain industries may very well have one property in common; both are growing rapidly while having the potential to revolutionize their respective fields. However, up until now, pioneers within the two industries have not yet found a common interest. That could soon change as projects have started embracing the idea of integrating the blockchain into the cloud computing sector, and we could soon see a future of endless possibilities.
The game-changing development could mean big things for both industries. The development of the cloud computing sector has been aided by several elements, including the increasing use of mobile devices and data storage and processing capability. However, the integration of blockchain technology into the cloud computing industry could turn out to be one of the most significant drivers of the age of cloud computing.
According to Intel the Meta’s vision of the Metaverse is impossible with the current Hardware limitations. But Intel said that they plan on increasing the performance of their CPU’s and GPU’s by close to 1,000 times in the hopes of reaching petaflop performance on regular consumer hardware to allow for photorealistic simulations inside the Metaverse.

Highly anticipated: Speculation around AMD’s new 3D V-Cache technology has swirled ever since Dr. Lisa Su gave us a sneak peek at Computex 2021. Since then, AMD and tech enthusiasts have remained cautiously optimistic regarding claims that the new chiplet-stacking approach can yield substantial performance gains with minimal impact to latency, responsiveness, and overall functionality. A recent test of an EPYC processor with V-Cache is giving early indication that AMD’s performance uplift claims may just hold true.
No one was quite sure what to expect when AMD announced their 3D V-Cache technology at Computex last summer. While some enthusiasts saw the substantial increase in cache as an exciting development, others in the community found themselves upset that the new offerings would not offer substantial increases in clock speed, improvements in power draw, etc. Last Friday tech news outlet Chips and Cheese published results of their initial testing with one of AMD’s new Milan-X processors with 3D V-Cache, the server-oriented EPYC 7V73X. And so far, things look promising.
According to the site’s summary, AMD has managed to substantially increase a processor’s cache size (768MB) in comparison to the previous Milan family of processors (256MB). Testing by Chips and Cheese reports impressive performance from the stacked CPU and much larger L3 cache without incurring any significant increase to cache and memory latency. Initial testing shows the latency penalty keeping the increase somewhere between three to four cycles.
Moke International makes the car in Britain before final assembly in France. The revised chassis has been re-engineered to accommodate four passengers, and look for an all-electric version to be released in the summer. Priced from around $30,000, the Moke can be customized with a choice of 13 colors, including eye-popping Flamingo Pink and Florida Orange. My tester also wears gleaming chrome trim and badging on the hood.
Other stylistic touches include leather hood straps and a retro radio, which is actually able to be heard above the wind noise, at least at speeds below 45 mph. And on a wet day, with weather equipment in place, the windscreen can be heated for improved visibility. In all, this upgraded version is not far off from Sir Alec’s initial car—basic in the extreme and as quintessentially British as fish and chips or a warm pint of beer.
