A team from IBM Research has created the world's smallest magnetic memory bit using only 12 atoms. This is significantly less than today's disk drives which use about 1million atoms to store a single ...

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 ...

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 ...

It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the ...

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 ...
