We plan to develop circuits using these new elements and demonstrate the coherent operation of an artificial atom
in cQED in the presence of a strong magnetic field.
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.
He explained that in this work they operated a quantum circuit as a more complicated artificial atom
with up to five energy levels.
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.
Horst Stormer, Ashoori's co-worker at AT&T, added: "You can make any kind of artificial atom
- long, thin atoms and big, round atoms.
Namely, we plan to exploit the potential of cavity quantum electrodynamics in the bad emitter limit where decoherence is mostly due to the artificial atom
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.
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.
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.
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.
Ashoori described the fabrication of an artificial atom
and the result of adding electrons to it one by one this week in Boston at a meeting of the American Association for the Advancement of Science.
We discovered that by sculpting a unique artificial vacuum inside a photonic crystal, we can completely control the electronic state of artificial atoms
within the vacuum," said Ma, a PhD student under John's supervision and lead author of a study.
