Physicists in Netherlands and Japan are the first to flip the value of a magnetic memory bit by firing a very short pulse of circularly-polarized laser light at it. Unlike other magneto-optic data ...

The device's polished-brass bit driver accommodates any third-party quarter-inch screwdriver bit, which is held in place by an integrated magnet. That said, a set of 10 system-specific bits is ...

In the drive to cram ever more information into handy data-storage devices, researchers have reduced the size of a bit of data to the ultimate limit—a single atom (Nature 2017, DOI: ...

Magnetic media, in the form of disk and tape drives, has been the dominant way of storing bits. But the speed and low power of flash memory has been displacing it from consumer systems, and various ...

Data encryption typically relies on the practical difficulty of a process called prime factorization. In this process, a huge number (represented by 1,024 or more bits) is decomposed into a product of ...
