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.

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.

Continuing the wave of extraordinary digital art sales manifested by new blockchain-based NFT technology, an artwork co-created by the famous humanoid robot Sophia has now sold for just under US$700,000.

A team of scientists at the University College London has used 3D tomography to shed new light on the Antikythera Mechanism – the world's first computer, which was an accurate model of the Cosmos as it was known to the ancient Greeks.

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.

A rare piece of cyber history that helped usher in the modern computer age is going up for sale as RR Auction's Steve Jobs + Apple Auction offers a functioning Apple-1 computer from the 1970s, complete with its original box signed by Steve Wozniak.

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.

Engineers at EPFL have created a new computer chip that can both process and store data in the same circuit. It’s made using a two-dimensional material called molybdenum disulfide, paving the way for smaller and more energy efficient electronics.

Desktop computers can get rather bulky, which is unnecessary for people who just need to access the internet or do office work. If a mini PC takes up too much space for you, the new Raspberry Pi 400 packs a whole home computer into just a keyboard.
