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'.
Quantum simulators explained
Everything you ever wanted to know about quantum simulators summed up in a new review from EPJ Quantum Technology.
Electrons moving in a magnetic field exhibit strange quantum behavior
The dynamic behavior of electrons in magnetic fields is crucial for understanding physical processes, such as the quantum Hall effect, which are important in many areas of solid state physics, including electrical ...
Unleashing the power of quantum dot triplets
Quantum computers have yet to materialise. Yet, scientists are making progress in devising suitable means of making such computers faster. One such approach relies on quantum dots—a kind of artificial atom, ...
Physicists Use Computer Models to Reveal Quantum Effects in Biological Oxygen Transport
(Phys.org) —Physicists have created a unique combination of computer models, based on the theory of quantum mechanics, and applied them to a previously well characterised protein found in muscle to develop a new picture ...
Highway for ultracold atoms in light crystals
When a superconductor is exposed to a magnetic field, a current on its surface appears which creates a counter field that cancels the magnetic field inside the superconductor. This phenomenon, known as "Meissner-Ochsenfeld ...
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.
A matter of matter: Demonstrating destructive quantum interference using Bose-Einstein condensates
Best of Last Week – Onset of mass investigated, wormhole time travel possibility and net encryption cracked in two hours
Particles near absolute zero do not break the laws of physics after all
In theory, the laws of physics are absolute. However, when it comes to the laws of thermodynamics—the science that studies how heat and temperature relate to energy—there are times where they no longer seem to apply. ...
Micro-macro entangled 'cat states' could one day test quantum gravity
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 ...
