Ultrashort laser pulses reveal that 'coherence' plays a subtle role in energy transfers Sophisticated recent experiments with ultrashort laser pulses support the idea that intuition-defying quantum interactions between molecules help plants, algae, and some bacteria efficiently gather light to fuel their growth. But key details of nature's vital light-harvesting mechanisms remain obscure, and the exact role that quantum physics may play in understanding them is more subtle than was once...

International Research Team Shows Distant Artificial Atoms Cooperate By Sharing Light
2013-11-14 15:52:07

University of Calgary Work is expected to have future applications in advanced quantum devices An international team of scientists has shown for the first time that atoms can work collectively rather than independently of each other to share light. Quantum physicists have long discussed such an effect, but it has not been seen before in an experiment. The team included scientists from ETH Zürich (a leading university in Switzerland) who performed the experiment and theoretical...

Physicists at the University of Basel have been successful in generating photons - the quantum particles of light – with only one color. This is useful for quantum information. The scientists have actively stabilized the wavelength of the photons emitted by a semiconductor thereby neutralizing the charge noise in the semiconductor. The results were developed in close collaboration with the Universities of Bochum, Paderborn and Lyon and have been published in the magazine Physical Review X....

For the past eight years, two French researchers have been bouncing droplets around a vibrating oil bath and observing their unique behavior. What sounds like a high-school experiment has in fact provided the first ever evidence that the strange features of the quantum world can be reproduced on a macroscopic scale. Now, many researchers are asking if the oil-bath experiments can provide insights into quantum mechanics and more specifically why particles can behave as waves and waves can...

Like any task, there is an easy and a hard way to control atoms and molecules as quantum systems, which are driven by tailored radiation fields. More efficient methods for manipulating quantum systems could help scientists realize the next generation of technology by harnessing atoms and molecules to create small but incredibly powerful devices such as molecular electronics or quantum computers. Of course, controlling quantum systems is as painstaking as it sounds, and requires scientists...

A quantum computer can solve tasks where a classical computer fails. The question how one can, nevertheless, verify the reliability of a quantum computer was recently answered in an experiment at the University of Vienna. The conclusions are published in the reputed scientific journal Nature Physics. The harnessing of quantum phenomena, such as superposition and entanglement, holds great promise for constructing future supercomputers using quantum technology. One huge advantage of such...
