Large-Scale Simulations Of The Brain May Need To Wait For Quantum Computers

Posted by in categories: computing, neuroscience, quantum physics

And, we have Quantum Computers of course, and they’ll be radically more advanced by 2025.


Why quantum computers, if successfully built, might be what neuroscientists need to carry out large multi-scale simulations of the brain. In fact, it will likely be impossible to do so without them, or some computationally equivalent technology.

Quantum Computers Check Each Other’s Answers in New Error-Correction Approach

Posted by in categories: computing, quantum physics

Quantum computers may be now able to employ a “call-a-friend” tactic to make sure their answers are correct.

In a study published today in Physical Review X, a team of physicists from Vienna, Innsbruck, Oxford, and Singapore designed an error-correction method that lets quantum computers check each other’s answers. While quantum computers are advancing quickly, the devices are still extremely sensitive to outside influences — like heat and cosmic rays — that make them more prone to errors that affect their computations, according to the researchers.

“In order to take full advantage of future quantum computers for critical calculations we need a way to ensure the output is correct, even if we cannot perform the calculation in question by other means,” said Chiara Greganti, a physicist at the University of Vienna.

GM shutting down production at most of its plants in North America

Posted by in categories: computing, transportation

General Motors will shut production at most of its North American plants for a week or two starting next week as the worsening chip shortage takes another bite out of its plans.

GM and other automakers had hoped the chip shortage would be mostly behind them by now. But the surge in Covid cases, especially in Southeast Asia where many of the chip manufacturers are based, has actually created a worsening problem for automakers.

Only a small handful of GM’s plants will remain in operation during the pause. Those plants make full-size SUVs and pickups, as well as some of its sports cars, such as the Camaro and Corvette. That’s because GM is prioritizing the chips it does have on hand for its most popular and profitable vehicles.

AMD files teleportation patent to supercharge quantum computing

Posted by in categories: computing, quantum physics, time travel

That’s teleportation for Qubits, not for humans, sadly.


AMD has proposed a patent for ‘teleportation,’ meaning things could be about to get much more efficient around here. With the incredible technological feats humanity achieves on a daily basis, and Nvidia’s Jensen going off on one last year about GeForce holodecks and time machines, it’s easy for us to slip into a headspace that lets us believe genuine human teleportation is just around the corner.

“Finally,” you sigh, mouthing the headline to yourself. “Goodbye work commute, hello popping to Japan for an authentic Ramen on my lunch break.”

Unraveling quantum interactions of 100,000 atoms in gases

Posted by in categories: computing, particle physics, quantum physics

Silvia Musolino defended her Ph.D. on new theoretical insights in quantum physics by studying gases at the lowest temperatures consisting of many atoms.

A practical way to study is provided by gases that have extremely low density and consist of many , often more than one hundred thousand, cooled down to temperatures close to the absolute zero. Silvia Musolino studied different types of interactions between these atoms, providing new pathways for future research on new technologies such as quantum computers.

Quantum mechanical laws govern the physics at the atomic scale and is distinguished by , which deals mainly with we can see, hear, or touch. However, even quantum mechanics influences our daily life. Transistors, which are crucial components of electronic devices, are based on quantum mechanical effects. Moreover, quantum mechanics paves the way for new technologies that may strongly impact our lives, such as quantum computers.

GM to halt production at nearly all North America assembly plants due to new chip problem

Posted by in categories: biotech/medical, computing

General Motors will idle nearly all its assembly plants in North America starting Monday as the COVID-19 pandemic affects production of semiconductor chips overseas.

GM said its Arlington Assembly in Texas, where it makes its highly profitable full-size SUVs, will run regular production next week, along with Flint Assembly, where it makes its heavy-duty pickups, Bowling Green Assembly in Kentucky, where it makes its Corvette, and a portion of Lansing Grand River Assembly, where it will make some Chevrolet Camaro and Cadillac Blackwing cars.

But all other assembly plants in North America will idle starting Monday.

Paving the path to electrically-pumped lasers from colloidal-quantum-dot solutions

Posted by in categories: biotech/medical, chemistry, computing, quantum physics, wearables

In a new review article in Nature Photonics, scientists from Los Alamos National Laboratory assess the status of research into colloidal quantum dot lasers with a focus on prospective electrically pumped devices, or laser diodes. The review analyzes the challenges for realizing lasing with electrical excitation, discusses approaches to overcome them, and surveys recent advances toward this objective.

“Colloidal quantum dot lasers have tremendous potential in a range of applications, including integrated optical circuits, wearable technologies, lab-on-a-chip devices, and advanced medical imaging and diagnostics,” said Victor Klimov, a senior researcher in the Chemistry division at Los Alamos and lead author of the cover article in Nature Photonics. “These solution-processed quantum dot present unique challenges, which we’re making good progress in overcoming.”

Heeyoung Jung and Namyoung Ahn, also of Los Alamos’ Chemistry division, are coauthors.
