Scientists have for the first time demonstrated improvement in quantum computers by using codes designed to detect and discard errors in the logic gates of such machines. The codes were applied to ...

It was 109 years ago, in the early spring of 1903, that Nikola Tesla, one of the world's most renowned inventors, filed specifications for two patents claiming the invention of logic gates, a ...

Current silicon gates are pure logic -- on or off, billions of times per second. In magnetologic gates, there are two magnetic electrodes that magnetically store data -- like a hard drive ...

A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate that was previously developed at Skoltech can operate at a speed of 240 ...

Importantly the two-qubit logic gate, demonstrated by the UNSW researchers, uses the same device technology as existing silicon chips so is expected to be much easier to manufacture as a full ...
