A major milestone has just been reached in quantum computing.

Three separate teams around the world have passed the 99 percent accuracy threshold for silicon-based quantum computing, placing error-free quantum operations within tantalizing grasp.

In Australia, a team led by physicist Andrea Morello of the University of New South Wales achieved 99.95 percent accuracy with one-qubit operations, and 99.37 percent for two-qubit operations in a three-qubit system.

Quantum computers aren’t quite ready for the home lab, but since there are ways to connect to some over the Internet, you can experiment with them more easily than you might think. [Norbert] decided to interface a giant quantum computer to an ordinary Arduino. Why? Well, that isn’t necessarily clear, but then again, why not? He explains basic quantum computing and shows his setup in the video below.

It’s unclear whether or not the new Ryzen-based systems can run Crysis.

On Tuesday, January 4, Panasonic announced that Redwood Materials would start supplying copper foil to its battery production facility in Giga Nevada. The Japanese tech giant announced the news during the 2022 CES tech trade show.

“Our work together to establish a domestic circular supply chain for batteries is an important step in realizing the full opportunity that EVs have to shape a much more sustainable world,” said Allan Swan, the President of Panasonic Energy of North America, at the latest CES tech trade show.

Redwood Materials, which former Tesla CTO JB Straubel founded, will be supplying Panasonic with copper foil made from recycled materials. The company recycles scripts from discarded electronics like cell phone batteries, laptops, power tools, and even scooters and electric bicycles. Redwood extracts materials like cobalt, nickel, and lithium, which are usually mined, from discarded electronics.

In response to pressure from right-to-repair advocates, Microsoft has released a new teardown video for its Surface Laptop SE.

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.

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.
