Study explains how Maxwell's demon uses mutual information to extract work
Duality principle is 'safe and sound': Researchers clear up apparent violation of wave-particle duality
Decades of experiments have verified the quirky laws of quantum theory again and again. So when scientists in Germany announced in 2012 an apparent violation of a fundamental law of quantum mechanics, a physicist at the University ...
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'.
X-ray laser probes tiny quantum tornadoes in superfluid droplets
An experiment at the Department of Energy's SLAC National Accelerator Laboratory revealed a well-organized 3-D grid of quantum "tornadoes" inside microscopic droplets of supercooled liquid helium – the ...
Molecular engineers record an electron's quantum behavior
A team of researchers led by the University of Chicago has developed a technique to record the quantum mechanical behavior of an individual electron contained within a nanoscale defect in diamond. Their technique ...
Beyond six nines: Ultra-enriched silicon paves the road to quantum computing
(Phys.org) —Using a relatively straightforward technique, a team of NIST researchers has created what may be the most highly enriched silicon currently being produced. The material is more than 99.9999% ...
Ion duet offers tunable module for quantum simulator
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a pas de deux of atomic ions that combines the fine choreography of dance with precise individual control.
Planting imperfections at specific spots within diamond lattice could advance quantum computing
By carefully controlling the position of an atomic-scale diamond defect within a volume smaller than what some viruses would fill, researchers have cleared a path toward better quantum computers and nanoscale ...
Physics research removes outcome unpredictability of ultracold atomic reactions
Findings from a physics study by a Kansas State University researcher are helping scientists accurately predict the once unpredictable.
'Cavity protection effect' helps to conserve quantum information
The electronics we use for our computers only knows two different states: zero or one. Quantum systems on the other hand can be in different states at once, they can store a superposition of "zero" and "one". ...
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 ...
Diamonds are a quantum computer's best friend
A new kind of quantum computer is being proposed by scientists from the TU Wien (Vienna) and Japan (National Institute of Informatics and NTT Basic Research Labs).
Physicists introduce another quantum animal: The Quantum Pigeon
Recently physicists at Chapman University's Institute for Quantum Studies introduced the Quantum Cheshire Cat. Now they have introduced another quantum animal: the Quantum Pigeon.
MRI for a quantum simulation
Magnetic resonance imaging (MRI), which is the medical application of nuclear magnetic resonance spectroscopy, is a powerful diagnostic tool. MRI works by resonantly exciting hydrogen atoms and measuring ...
