Physicists Detect Single-Electron Tunneling with Quantum Dots
(PhysOrg.com) -- Detecting the coherent motion of a single electron is a challenge, for the simple reason of scale: the timescale of the coherent motion of a single-electron wave function is in the picosecond regime (one ...
Exerting better control over matter waves
(PhysOrg.com) -- “The concept of matter waves is at the heart of quantum mechanics,” Oliver Morsch tells PhysOrg.com. “At the beginning of the last century, scientists discovered that solid particles could exhibit properties ...
