From 1994 on, I built my own computers. I did the specs, I got the bits, I put them together, and I built other people's computers. Hardly a month would go by without me having my head inside yet ...

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 128 bits as a single unit, compared to 8, 16, 32 or 64 bits. There are no 128-bit CPUs on the market and there may never be because there is no practical reason for doubling the ...

Deep learning is an inefficient energy hog. It requires massive amounts of data and abundant computational resources, which explodes its electricity consumption. In the last few years, the overall ...

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 ...

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 ...

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 ...
