For the first time, scientists have used sound to ‘talk’ to an artificial atom, demonstrating a curious phenomenon in quantum physics that sees sound waves take on the role of light.
The interaction between atoms and light is well known and has been studied extensively in the field of quantum optics.
However, to achieve the same kind of interaction with sound waves has been a more challenging undertaking.
The researchers at the Chalmers University of Technology in Sweden have now succeeded in making acoustic waves couple to an artificial atom.
"We have opened a new door into the quantum world by talking and listening to atoms," said Per Delsing, head of the experimental research group.
Burger King’s plans to merge with Tim Hortons show the stark differences of how workers are treated in the US, UK and Canada
If Louis Pasteur were to come out of his grave because he heard that the cure for cancer still had not been found, NIH would tell him, “Of course we’ll give you assistance. Now write up exactly what you will be doing during the three years of your grant.” Pasteur would say, “Thank you very much,” and would go back to his grave. Why? Because research means going into the unknown. If you know what you are going to do in science, then you are stupid! This is like telling Michelangelo or Renoir that he must tell you in advance how many reds and how many blues he will buy, and exactly how he will put those colors together.
Astronomers have detected a mysterious signal in X-ray data from a study of galaxy clusters, and they think the X-rays could have been produced by the decay of sterile neutrinos, a type of particle proposed as a candidate for dark matter…
