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.
