Quantum technologies are still far in the future; indeed, although the first examples of quantum computers and quantum cryptography have been described, the path towards their large-scale implementation is still very long. One of the most promising components upon which to base these new technologies are quantum dots, small crystals of a few millionths of a millimeter, whose study is carried out in all the largest research centers in the world.
Researchers at the Department of Physics and Astronomy coordinated by Francesco Biccari - in collaboration with research teams led by Marco Felici at Sapienza University of Rome and by Giorgio Pettinari at the Institute of Photonics and Nanotechnology of CNR in Rome - have shown the possibility of creating quantum dots thanks to a simple laser writing technique that allows to control both the position and the wavelength of the emitted light. The work was published in Advanced Materials.
