Heat is a major hurdle for electronic devices. Scientists have now found that nanowires made of a certain isotope of silicon can conduct heat 150 percent better than regular silicon, potentially leading to drastically cooler computer chips.

Researchers have now developed the fastest logic gates ever created, by zapping graphene and gold with laser pulses. The new logic gates are a million times faster than those in existing computers, demonstrating the viability of “lightwave electronics.”

Apple has unveiled new desktop computers and monitors at its keynote presentation today. The Mac Studio is a new desktop workstation running on a powerful new processor, and the Studio Display is a new ultra-HD Retina screen.

Researchers have demonstrated key tech that could help scale up quantum computers, creating a model with a record-breaking 512 qubits. The team combined atoms of two elements into an array, so atoms can be manipulated without disturbing their neighbors.

Meta has unveiled the AI Research SuperCluster (RSC), a new supercomputer that’s among the fastest in the world. And it’ll only get faster – by the end of the year it should rank number one, with computing power on the exascale.

Quantum computers are so far held back by their complexity. Engineers at Stanford have now demonstrated a new relatively simple design for a quantum computer where a single atom is entangled with a series of photons to process and store information.

IBM has unveiled the Eagle, the world’s most powerful quantum processor. Boasting 127 quantum bits (qubits), the Eagle is a major step towards commercial quantum computers outperforming traditional machines.

One of the first personal computers ever sold – a 1976 Apple-1 – fetched US$500,000 at auction yesterday, but it might well be one of the auction bargains of the year.

For now, quantum computers are mostly limited to labs and big experimental setups. But Japanese researchers have now made a step towards more accessible quantum computing devices, finding a way to “twist” light at room temperature.

As revolutionary as they could be, quantum computers still have a few issues, such as controlling more than a few dozen qubits. Now researchers have found a way to control potentially millions of qubits at once, by adding a crystal prism to the chip.

A new computer processor called Morpheus thwarts hackers by randomly changing its microarchitecture every few milliseconds. The puzzling processor has now aced major tests, repelling hundreds of professional hackers in a DARPA security challenge.

Highlighting the march of technology, IBM has unveiled new semiconductor chips with the smallest transistors ever made. The new 2- nanometer tech allows the company to cram a staggering 50 billion transistors onto a chip the size of a fingernail.
