Silicon Valley startup Lightmatter unveils a revolutionary computer chip using light to accelerate AI tasks and reduce energy ...

We all know, at least intellectually, that our computers are all built with lots of tiny transistors. But beyond that it’s a little hard to describe. They’re printed on a silicon wafer somehow ...

By Stephen Nellis SAN FRANCISCO (Reuters) -Silicon Valley startup Lightmatter revealed on Wednesday it had developed a new ...

Computers that use photons rather than electrons to manipulate data promise greater speed and energy efficiency, and the ...

If transistors could replace vacuum tubes in the phone system, then they certainly could replace them in computers too. The army, with its need for ever-faster and more efficient calculations ...

Two companies have announced photonic devices that could solve specific real-world problems faster and with less energy than conventional computers.

The rule states that the number of transistors on a computer chip doubles about every 18 months, driving rapid progress in computers and telecommunications. Doubling the number of devices that can fit ...

Engineers and physicists at UCL have developed a new fabrication process for building quantum computers that achieves an ...

Two tech companies have introduced laser light-based computer components, promising faster processing and lower energy ...

and some past experience of building computers on perfboard from discrete transistors, so this next project, Q2, is a complete implementation of a PDP8-like microcomputer on a single PCB.

That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology. It was built by Walter Brattain. Before ...

As an essential part of a broad spectrum of electronic devices such as computers, smartphones, and other consumer electronics, transistors play a vital role in driving technological progress.
