At the heart of all computers is a clock, a dedicated timepiece ensuring that all of the parts of the computer are synchronized and can work together to execute the instructions that the computer ...

The computing world is on the cusp of a transformative leap forward, as researchers at the California Institute of Technology (Caltech) have unveiled an all-optical computer capable of achieving clock ...

Before today, we probably would have said that scratch-built relay computers were the sole domain of only the most wizardly of graybeards. But this impressive build sent in by [Will Dana] shows that ...

In 2012, two servers run by the U.S. Navy rolled back their clocks 12 years, deciding it was the year 2000. The servers were very important: they’re part of a worldwide network that helps computers ...

Reader Dan loves his Asus netbook–but not its clock. Every time he turns the machine off, it seems to lose a couple hours. But the minutes, he notes, remain accurate. There are a number of reasons a ...

Is the clock on every computer system in your organization set to the correct time? If your answer is no, you’re not alone. According to a 2007 study by Florian Buchholz and Brett Tjaden, both ...

The oversampling regime of an exemplary clock—a pendulum in a weakly lit environment. The two sources of entropy production for this clock are: the friction within the clockwork itself, and the matter ...

There are different ideas about how quantum computers could be built. But they all have one thing in common: you use a quantum physical system - for example individual atoms - and change their state ...
