Silicon spin qubits gain ground as a leading candidate for quantum computing
In the rapidly evolving field of quantum computing, silicon spin qubits are emerging as a leading candidate for building scalable, fault-tolerant quantum computers.
A new review titled “Single-Electron Spin Qubits in Silicon for Quantum,” published in Intelligent Computing, highlights the latest advances, challenges and future prospects of silicon spin qubits for quantum computing.
Silicon spin qubits are compatible with existing semiconductor industry manufacturing processes, making them promising for universal quantum computers. They have several remarkable properties.
From Blockchain to Brainwaves: Coinbase Co-Founder Fred Ehrsam Enters the Neurotech Race with Non-Invasive BCI Startup Nudge
Fred Ehrsam, billionaire co-founder of Coinbase, is shifting his next big bet from cryptocurrency to the human brain, unveiling a non-invasive brain-computer interface designed to modulate brain activity with sound waves.
Ehrsam’s entry as the latest competitor to join the race to develop accessible brain-computer interfaces (BCIs) follows similar recent efforts from tech leaders like Elon Musk, Jeff Bezos, and Bill Gates.
On April 8, Ehrsam’s startup, Nudge, unveiled its first product, the Nudge Zero. A noninvasive brain interface device that uses ultrasound to modulate brain activity, the technology represents the first start-up venture to pursue this unique approach with BCI technology.
Dynamic visualizations expose how domain walls shift in ferroelectrics
As demand for energy-intensive computing grows, researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a new technique that lets scientists see—in unprecedented detail—how interfaces move in promising materials for computing and other applications. The method, now available to users at the Center for Nanophase Materials Sciences at ORNL, could help design dramatically more energy-efficient technologies.
The research is published in the journal Small Methods.
Data centers today consume as much energy as small cities, and that usage is skyrocketing. To counter the trend, scientists are studying exotic materials such as ferroelectrics that could store and process information far more efficiently than silicon, which is traditionally used. But realizing the potential depends on understanding the processes occurring at dimensions thousands of times smaller than a human hair —specifically, at the ferroelectric material’s domain walls, which are the boundaries between areas of the material that exhibit different magnetic or electric properties.
Gravity could be the definitive clue that the universe is a computer
Modern ideas about reality sometimes sound like a wild story. The notion that everything around us might be bits and bytes is easy to brush aside, yet it continues to intrigue many curious minds.
This perspective has led some researchers to wonder if physical forces might be signals of an underlying information system.
According to physicist Melvin M. Vopson of the University of Portsmouth, certain features of gravity may hint at information contained in a universal computational code.
