Quantum Hot Potato: Researchers Entice Two Atoms to Swap Smallest Energy Units
February 23, 2011 — Physicists have for the first time coaxed two atoms in separate locations to take turns jiggling back and forth while swapping the smallest measurable units of energy. By directly linking the motions ... > full story -
Quantum Simulator Becomes Accessible to the World
February 23, 2011 — Experimental physicists have put a lot of effort in isolating sensitive measurements from the disruptive influences of the environment. In an international first, Austrian quantum physicists have ... > full story -
Atomic Antennas Transmit Quantum Information Across a Microchip
February 23, 2011 — New research suggests a fundamentally novel architecture for quantum computation. They have experimentally demonstrated quantum antennas, which enable the exchange of quantum information between two ... > full story -
Milestone in Path to Large-Scale Quantum Computing Reached: New Level of Quantum Control of Light
February 15, 2011 — An important milestone toward the realization of a large-scale quantum computer, and further demonstration of a new level of the quantum control of light, were just ... > full story -
Physicists Isolate Bound States in Graphene-Superconductor Junctions
February 14, 2011 — Researchers have documented the first observations of some unusual physics when two prominent electric materials are connected: superconductors and graphene. When sandwiched between superconductors, ... > full story -
Physicists Challenge Classical World With Quantum-Mechanical Implementation of 'Shell Game'
January 31, 2011 — Inspired by the popular confidence trick known as "shell game," researchers have demonstrated the ability to hide and shuffle "quantum-mechanical peas" -- microwave single photons -- under and ... > full story -
Graphene and 'Spintronics' Combo Looks Promising
January 25, 2011 — A team of physicists in China has taken a big step toward the development of useful graphene spintronic ... > full story -
Ultrafast Quantum Computer Closer: Ten Billion Bits of Entanglement Achieved in Silicon
January 22, 2011 — Scientists have made a significant step towards an ultrafast quantum computer by successfully generating 10 billion bits of quantum entanglement in silicon for the first time -- entanglement is the ... > full story -
Single Photon Management for Quantum Computers
January 20, 2011 — The quantum computers of tomorrow might use photons, or particles of light, to move around the data they need to make calculations, but photons are tricky to work with. Two new papers point to ways ... > full story -
Quantum Quirk Contained: Discovery Moves Quantum Networks Closer to Reality
January 12, 2011 — Researchers are working on a way to make quantum networks a reality. They have demonstrated, for the first time, that a crystal can store information encoded into entangled quantum states of ... > full story -
Better Control of Building Blocks for Quantum Computer
December 23, 2010 — Scientists in the Netherlands have succeeded in controlling the building blocks of a future super-fast quantum computer. They are now able to manipulate these building blocks (qubits) with electrical ... > full story -
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
