A massive optical computer being built could outpace quantum computers

New Scientist

The device, which is being built by Hiroyuki Tamura and colleagues at Japanese tech firm NTT, is specially designed to solve optimisation problems.

Scientists prove it's possible to build a DNA computer


Current computers use a finite number of processors to perform these sorts of operations. A device that uses DNA molecules can grow more of itself to perform many calculations simultaneously, seemingly without limit. Quantum computers, still in their infancy, can also process concurrently, but still need specific set ups to do so, which limits their usefulness. DNA computers have no such constraint. "Imagine a computer is searching a maze and comes to a choice point, one path leading left, the other right," Professor King told Popular Mechanics, "Electronic computers need to choose which path to follow first.

Mini computers that fit in the palm of your hand


Want a computer that doesn't take up a good sized chunk of your desk? Here are a selection of PCs running a variety of operating systems -- Windows, Linux, Android, and Mac -- with price tags and system specifications to suit all needs. All the above computers are small enough that you can hold them in your hand, and many offer features such as fanless cooling and the ability to be used for embedded projects.

HP computer stranded in space


Two HP servers sent up to the International Space Station in August 2017 as an experiment have still not come back to Earth, three months after their intended return. Together, they make up the Spaceborne Computer, which operates on the open-source Linux system and has supercomputer processing power. They were sent up to see how durable they would be in space with minimum specialist treatment. After 530 days, they are still working. Their return flight was postponed indefinitely, after a Russian rocket fail in October 2018.

Five Ways Quantum Computing Can Change the World.


There's been a lot of talk about quantum computing lately as Googles recent claim to "Quantum Supremacy" is making the media rounds. With increasingly powerful quantum computers now available for programmers to utilise in the cloud, it's important to learn about the benefits and challenges quantum computing will bring to your company. So why is quantum computing such a big deal? Here are five key areas quantum computing is set to revolutionise. With quantum computings raw power you can see how artificial intelligence will come alive.
