Sam Zeloof, 21 builds homemade semiconductors in his family’s garage in Flemington, N.J. (In his latest video, Zeloof refers to it casually as his “garage fab.”) The Carnegie Mellon University student has been doing it since high school, becoming a truly inspiring example of just how far a do-it-yourself spirit can take you.

And best of all, he’s documented it all in detailed blog posts and nearly 50 videos uploaded to YouTube, sharing what he’s learned for others who might follow in his footsteps.

“I hope that my success will inspire others,” Zeloof writes in an early blog post, “and help start a revolution in home chip fabrication. Let’s democratize the tools of innovation.”

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 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.

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.

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.”

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.
