In a recent paper published in Science, the chief writer Martin Gustafasson explains how an artificial atom and “the weediest sound that can be distinguished” form a device for studying quantum behaviour. An artificial atom can be described as a specific substantial prepared to act electronically like a particular atom. An artificial atom can be shaped from millions of billions of atoms, but share the atomic feature that they grip definite amounts of energy and may then discharge this energy as light. In an introductory research paper issued in a July edition of Physical Review A, a sub-group of the Science writers note that a vital property of atoms is that they are much smaller than even the wavelength of optical light, constructing them to look like a point. To attain the similar outcome with developments made from multiple atoms, it is essential to use the lengthier wavelengths of microwave radiation. The writers reflected the probability of consuming sound waves as an alternative of the electromagnetic spectrum and debated what would be anticipated if these were joined to artificial atoms.

Gustafsson of Sweden's Chalmers University of Technology says “Due to the slow speed of sound, we will have time to control the quantum particles while they travel. This is difficult to achieve with light, which moves 100,000 times more quickly." Co-author Per Delsing states, “We have opened a new door into the quantum world by talking and listening to atoms.” Nonetheless, if the indication of conversing with the constructing blocks of matter appeals to you, you'll need a high-pitched voice; the group used a frequency of 4.8GHz, 20 octaves which is above the highest note on a piano. The group of researchers hope that they can use this new information to study how to regulate quantum behaviour better, counting the pursuit for electrical circuits and consequently computers, that work on quantum principles.
