Quantum physics: Swift control of a single spin
Keiichi Edamatsu1
Abstract
For now, quantum information processing systems remain a dream. Step by step, however, progress towards that goal is being made, with one promising route involving a novel means of manipulating electron spin.
The basic quantity of magnetic recording — the working principle of a computer's hard disk — is an electron's spin. Although the technology for magnetic recording is reaching recording densities as high as 1 terabit per square inch (ref.
