This book outlines the state of research on artificial atoms (new quasiatomic nanoheterostructures) formed from spatially separated electrons and holes and more complex structures based on them, and a new model of an artificial atom that explains its electronic properties.
Tokyo, Japan, Oct 4, 2007 - (JCN Newswire) - RIKEN, NEC Corporation, and JST ("Japan Science and Technology Agency") have successfully demonstrated a laser emission from one artificial atom by coupling superconducting quantum bits ("qubits") to a resonator.
And then, suddenly, there was the "artificial atom."

And now, a team of scientists - Geim and Novoselov included - have created an "artificial atom" in graphene that opens up possibilities for quantum computing.
He explained that in this work they operated a quantum circuit as a more complicated artificial atom with up to five energy levels.
Moreover, this artificial atom without a nucleus, as Gerald Gabrielse and his colleagues refer to their diminutive apparatus, promises to make possible the most precise measurements yet of certain fundamental constants.
Subsequently, billions of atoms in the nanometer thick conductors behave like a single artificial atom -- which can then become the quantum bit, or qubit, used in a computer.
TEHRAN (FNA)- Researchers succeeded in an experiment where they get an artificial atom to survive ten times longer than normal by positioning the atom in front of a mirror.
"One can consider the artificial atom as a tiny laboratory in which quantum mechanics and the effects of electron-electron interactions can be studied," says Raymond C.
