Exploring the realistic nature of the wave function in quantum mechanics
Jan 05, 2018
Quantum mechanics is a pillar of modern science and technology, and has benefited human society for a century. The wave function, also known as the quantum state, is the description of a quantum object and plays a central ...
Researchers chart the 'secret' movement of quantum particles
Dec 22, 2017
Researchers from the University of Cambridge have taken a peek into the secretive domain of quantum mechanics. In a theoretical paper published in the journal Physical Review A, they have shown that the way that particles ...
Study sheds new light on production of hydroxyl radicals, which help break down air pollutants
Dec 14, 2017
Residents in some areas of the developing world are currently coping with dangerous levels of air pollution. Recent research, co-led by the U.S. Department of Energy's (DOE) Argonne National Laboratory, is leading to a new ...
Research team saves information on a single molecule
Dec 07, 2017
Over the past few years, the building blocks of storage media have become ever smaller. But further miniaturization of the current technology is hindered by fundamental limits of quantum mechanics. A new approach consists ...
Experiment demonstrates quantum mechanical effects from biological systems
Dec 05, 2017
Nearly 75 years ago, Nobel Prize-winning physicist Erwin Schrödinger wondered if the mysterious world of quantum mechanics played a role in biology. A recent finding by Northwestern University's Prem Kumar adds further evidence ...
Scientists demonstrate one of largest quantum simulators
Nov 29, 2017
Physicists at MIT and Harvard University have demonstrated a new way to manipulate quantum bits of matter. In a paper published today in the journal Nature, they report using a system of finely tuned lasers to first trap ...
Scientists invent technique to map energy and momentum of electrons beneath a material's surface
Nov 16, 2017
For the first time, physicists have developed a technique that can peer deep beneath the surface of a material to identify the energies and momenta of electrons there.
New molecules for OLEDs and pharmaceuticals
Nov 14, 2017
Chemists from Ural Federal University (UrFU, Ekaterinburg) have suggested a new technique for synthesizing thiophene derivatives and studied their fluorescent properties experimentally as well as theoretically. Many organic ...
A new kind of quantum computer
Nov 06, 2017
Quantum mechanics incorporates some very non-intuitive properties of matter. Quantum superposition, for example, allows an atom to be simultaneously in two different states with its spin axis pointed both up and down, or ...
A bit of a 'quantum magic trick'—experiment shows how to speed up frequency measurement
Nov 02, 2017
An accurate analog clock tick-tick-ticks with a constant precision and well known frequency: one tick per second. The longer you let it tick, the better to test its accuracy —10 times as long corresponds to a ten-fold improvement ...
