We’ve seen our share of homebrew computers over the years. Usually, these bare-bone systems use a small, early 80s-era microprocessor such as the Z80 or 6502. These little 8-bit machines are awesome, ...

Imagine a world where people could only talk to their next-door neighbor, and messages must be passed house to house to reach far destinations. Until now, this has been the situation for the bits of ...

How would we handle metastability in our 4-bit computer if we were to implement it as a microcontroller chip, a single-board computer, or a cabinet-based system? Now, after laying all of this ...

There are many different ways in which we could implement our 4-Bit Chewy Computer — here are a few possibilities for you to peruse and ponder In my previous column on this topic — “Building a 4-Bit ...

CPUs that process 64 bits as a single unit, compared to 8, 16 or 32. Today's desktop and laptop computers are mostly 64-bit machines; however, there are countless 32-bit, 16-bit and 8-bit ...

Quantum mechanics allows for some very strange things, like the teleportation of information and computers that can break even the toughest codes. Subscribe to read this story ad-free Get unlimited ...

Using a powerful machine made up of 56 trapped-ion quantum bits, or qubits, researchers have achieved something once thought impossible. They have proven, for the first time, that a quantum computer ...

A team of computer engineers from quantum computer maker Quantinuum, working with computer scientists from Microsoft, has found a way to greatly reduce errors when running experiments on a quantum ...

A new version of the pocket-sized BBC micro:bit computer is coming to schools worldwide, packed with new features designed to keep young students up-to-date with the latest hot trends in technology.

I've got a shelf full of computer history books, many of which I love and have reread several times. But I wanted to write one that focused on the first real computer I grew up with, the one that ...

Milestone on the path to the quantum computer: Scientists of the University of Konstanz, Princeton University, and the University of Maryland have developed a stable quantum gate for two-quantum bit ...
