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 ...

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, ...

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 ...

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 ...

What we are going to do is design a simple 4-bit computer at the primitive logic gate and flip-flop level and then implement it in the technology of our choice I’ve often wondered what would happen if ...

With transmons and entanglement, scientists strive to put subatomic weirdness to work on the human scale. By Dennis Overbye YORKTOWN HEIGHTS, N.Y. — A bolt from the maybe-future struck the technology ...

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 ...

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 ...

In an important step forward in the quest to build a quantum computer using silicon-based hardware, researchers have succeeded in making possible the exchange of information between two qubits located ...
