Toward Heat-Free "Single-Atom Memory": University of Tokyo Demonstrates New Principle for Reading and Writing Data with Zero Electric Current
A research group at the University of Tokyo has developed, for the first time in the world, a technology that reads and writes the magnetic information of a single atom using only quantum mechanical "force," without using any electric current whatsoever. Because this method can prevent heat generation from Joule heating as well as malfunctions, it represents a groundbreaking achievement toward realizing the ultimate high-density memory.
