Computers

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.

Most of us can give Pi to four or five digits, but Swiss scientists have broken the world record. It took three and a half months and a data center’s worth of computer equipment, but the researchers calculated Pi to a staggering 62.8 trillion digits.

We've been harping on for two decades about how undervalued scientific and computer memorabilia is. Hence, we figure that we should alert our esteemed readership to an RR Auction heading for conclusion later this month, which includes some gems.

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.

Liquid cooling is one of the most effective ways to keep computers from overheating. Microsoft has now put a unique spin on the technique, demonstrating a system to cool its cloud servers by dunking the computers into a tank full of boiling liquid.

Seventy five years ago, the world was introduced to ENIAC, the first ever electronic, programmable, general purpose, digital computer, which not only ushered in the beginning of the computer age, but also shaped popular conceptions of the computer.

Teams tasked with managing tsunami risks may soon have a powerful new tool at their disposal, in the form of a new AI model that enables near real-time predictions of how these events will shape the flooding of coastal areas.

A quantum internet would be much faster and more secure than the regular web – and now it may be one step closer to reality. Scientists have used quantum teleportation to send information over long distances, with a higher fidelity than ever before.

Designed by computer pioneer Douglas Engelbart and licensed by Apple at the dawn of the personal computing era, the early three-button "X-Y" mouse is a rare and important piece of history.

A Chinese quantum computer called Jiuzhang has apparently achieved "quantum supremacy" – conducting a calculation in 200 seconds that would take a regular supercomputer a staggering 2.5 billion years to complete.

Engineers have created one of the smallest memory storage devices ever, made out of a 2D material measuring 1 nanometer square. The device works on the movements of single atoms, paving the way for memory systems with incredible information density.
