A 'Spin Ratchet' Paves the Way for Spin Computers: New Electronic Structure for Generating Spin Current
December 16, 2010 — Scientists have proposed and experimentally demonstrated a ratchet concept to control the spin motion. In analogy to a ratchet wrench, which provides uniform rotation from oscillatory motion, such ... > full story -
Science's Breakthrough of the Year: The First Quantum Machine
December 16, 2010 — Back in March, a group of researchers designed a gadget that moves in ways that can only be described by quantum mechanics -- the set of rules that governs the behavior of tiny things like molecules, ... > full story -
Computer Memory Takes a Spin: Physicists Read Data After Storing Them in Atomic Nuclei for 112 Seconds
December 16, 2010 — Physicists have stored information for 112 seconds in what may become the world's tiniest computer memory: magnetic "spins" in the centers or nuclei of atoms. Then the physicists retrieved and read ... > full story -
The Birth of Time: Quantum Loops Describe the Evolution of the Universe
December 16, 2010 — What was the Big Bang and what happened before it? Scientists have attempted to answer the question. Within the framework of loop quantum gravity they have put forward a new theoretical model, which ... > full story -
Single Quantum Dot Nanowire Photodetectors
December 14, 2010 — Moving a step closer toward quantum computing, researchers recently fabricated a photodetector based on a single nanowire, in which the active element is a single quantum dot with a volume of a mere ... > full story
