The search for deviations from standard quantum mechanics
Apr 21, 2017
Physicists have searched for deviations from standard quantum mechanics, testing whether quantum mechanics requires a more complex set of mathematical rules. To do so a research team led by Philip Walther at the University ...
Bell correlations measured in half a million atoms
Apr 17, 2017 feature
(Phys.org)—Physicists have demonstrated Bell correlations in the largest physical system to date—an ensemble of half a million atoms at an ultracold temperature of 25 µK. The presence of Bell correlations indicates that ...
New sensor devices recycle atoms
Apr 12, 2017
Next-generation sensors to be used in fields as diverse as mineral exploration and climate change will be turbo boosted thanks to University of Queensland and University of Sussex research.
The inner lives of molecules: New method takes 3-D images of molecules in action
Apr 04, 2017
Quantum mechanics rules. It dictates how particles and forces interact, and thus how atoms and molecules work—for example, what happens when a molecule goes from a higher-energy state to a lower-energy one. But beyond the ...
Quantum computers may have higher 'speed limits' than thought
Mar 27, 2017
How fast will a quantum computer be able to calculate? While fully functional versions of these long-sought technological marvels have yet to be built, one theorist at the National Institute of Standards and Technology (NIST) ...
In a quantum race everyone is both a winner and a loser
Mar 24, 2017
Our understanding of the world is mostly built on basic perceptions, such as that events follow each other in a well-defined order. Such definite orders are required in the macroscopic world, for which the laws of classical ...
ATP hydrolysis energy explained through large-scale hybrid quantum / classical simulations
Mar 22, 2017
In ATP hydrolysis, water is used to split apart adenosine triphosphate (ATP) to create adenosine diphosphate (ADP) to get energy. ATP hydrolysis energy (AHE) is then used in the activities of living cells.
From black holes to helium
Mar 21, 2017
A team of scientists has discovered that a law controlling the bizarre behavior of black holes out in space—is also true for cold helium atoms that can be studied in laboratories.
Researchers beat the quantum limit of microwave measurements
Mar 16, 2017
Research groups at Aalto University and the University of Jyväskylä have demonstrated a new microwave measurement method that goes to the quantum limit of measurement and beats it. The new method can potentially be used ...
