Physicists Explain How Human Eyes Can Detect Quantum Effects
Observing the Quantum Hall Effect in 'Real' Space
'Topological insulators' promising for spintronics, quantum computers
(Phys.org) —Researches have uncovered "smoking-gun" evidence to confirm the workings of an emerging class of materials that could make possible "spintronic" devices and practical quantum computers far more ...
What happens when ultracold atomic spins are trapped in an optical lattice structure
Every electrical device, from a simple lightbulb to the latest microchips, is enabled by the movement of electrical charge, or current. The nascent field of 'spintronics' taps into a different electronic ...
Superabsorbing ring could make light work of snaps
A quantum effect in which excited atoms team up to emit an enhanced pulse of light can be turned on its head to create 'superabsorbing' systems to make the 'ultimate camera pixel'.
Tunable quantum behavior observed in bilayer graphene
Columbia researchers have observed the fractional quantum Hall effect in bilayer graphene and shown that this exotic state of matter can be tuned by an electric field.
Quantum biology: Algae evolved to switch quantum coherence on and off
A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
How to test the twin paradox without using a spaceship
Forget about anti-ageing creams and hair treatments. If you want to stay young, get a fast spaceship. That is what Einstein's Theory of Relativity predicted a century ago, and it is commonly known as "twin ...
Quantum computing machine under scrutiny
A new and innovative computing machine is currently attracting a great deal of attention in specialist circles. A team under the leadership of Matthias Troyer, a professor at ETH Zurich, has now confirmed ...
Quantum mechanics explains efficiency of photosynthesis
Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous ...
Graphene can host exotic new quantum electronic states at its edges
(Phys.org) —Graphene has become an all-purpose wonder material, spurring armies of researchers to explore new possibilities for this two-dimensional lattice of pure carbon. But new research at MIT has found ...
The reins of Casimir: Engineered nanostructures could offer way to control quantum effect
You might think that a pair of parallel plates hanging motionless in a vacuum just a fraction of a micrometer away from each other would be like strangers passing in the night—so close but destined never ...
Large-scale quantum chip validated
A team of scientists at USC has verified that quantum effects are indeed at play in the first commercial quantum optimization processor.
