Quantum computing, the cutting-edge technology that promises unprecedented computational power, has taken a significant leap forward with the unveiling of a groundbreaking quantum chip by Amazon Web Services.

“It’s a custom-designed chip that’s totally fabricated in house by our AWS quantum team,” said Peter Desantis, senior vice president of AWS utility computing products, during a keynote address in Las Vegas at AWS’s re: Invent conference for the global cloud computing community.

DeSantis said the state-of-the-art chip represents a major milestone in the quest for error-corrected quantum computers. “We’ve been able to suppress errors by 100x by using a passive error correction approach,” he said.

The brain-computer interface (BCI) space continues to rise in notoriety, and a number of players are throwing their hats in the ring.

Such technologies could enable users to control a computer with their brain, or even go beyond that. Countless immobile people someday could control a mouse cursor, keyboard, mobile device/tablet, wheelchair or prosthetic device by only thinking.

Big names have already established their presence in the space. Elon Musk’s Neuralink continues to make headway, while Bill Gates-and Jeff Bezos-backed Synchron has an innovative catheter-delivered implant. Blackrock Neurotech, which has a next-generation BCI, has been implanting its Utah Array in patients since 2004.

It comes 3 years after Amazon debuted its ‘handy’ authentication service for consumers.

Amazon’s cloud computing subsidiary AWS (Amazon Web Services) has lifted the lid on a new palm-scanning identity service that allows companies to authenticate people when entering physical premises.

The announcement comes as part of AWS’s annual Re: Invent conference, which is running in Las Vegas for the duration of this week.

Amazon One Enterprise, as the new service is called, builds on the company’s existing Amazon One offering which it debuted back in 2020 to enable biometric payments in Amazon’s own surveillance-powered cashierless stores. Visitors to Amazon Go stores can associate their payment card with their palm-print, allowing them to enter the store and complete their transaction by hovering their hand over a scanner.

Physicists at Martin Luther University Halle-Wittenberg (MLU) and Central South University in China have demonstrated that, combining specific materials, heat in technical devices can be used in computing. Their discovery is based on extensive calculations and simulations. The new approach demonstrates how heat signals can be steered and amplified for use in energy-efficient data processing.

The team’s research findings have been published in the journal Advanced Electronic Materials (“PT-Symmetry Enabled Spintronic Thermal Diodes and Logic Gates.”).

Information signals are encoded as thermal spin waves (red arrows). Logical operations are realized with two magnetic strips (signal conductors) and precisely controlled with current pulses in a spacer (platinum). (Image: Berakdar group)

A high-tech soccer ball that helps with more accurate offside decisions will make its European Championship debut next year in Germany after being used at the 2022 World Cup.

European soocer governing body UEFA and manufacturer Adidas unveiled the ball for Euro 2024 in Berlin on Wednesday. It is named “Fussballliebe,” the German word for “love of soccer,” and will be used at next year’s 51-game tournament from June 14-July 14.

A fixed on a gyroscope inside the ball sends data 500 times per second to record the point at which it is kicked. The “kick point” helps match officials make offside decisions using multiple camera angles to create 3D visualizations that illustrate .
