... the occupancy of the quantum states," Klimeck says. "We can control the location of the electron in this artificial atom and, therefore, control the quantum state with an externally applied electrical ...
... of quantum physics is entered. In this circuit the behavior is something like an artificial atom (i.e. like the so-called quantum bits ("qubits") of quantum computers) and the ...
... but those 2-D materials have been limited to a single monolayer of artificial atoms whose light-bending properties cannot be defined. Thicker, 3-D metamaterials with negative ...
... broad frequency ranges. This procedure is "particularly relevant for studying the properties of artificial atoms," Oliver said.
Better knowledge of these superconducting structures could hasten the ...
New technique of 'amplitude spectroscopy' works at frequencies where conventional spectroscopy is difficult
... "The whole idea behind metamaterials is to create materials designed and engineered out of artificial atoms, meta-atoms, which are smaller than the wavelengths of light itself," Shalaev said. "One of ...
... temperatures, but the new atom-sized quantum dots perform at room temperature.
Often referred to as artificial atoms, quantum dots have previously ranged in size from 2-10 nanometers in diameter. ...
... structure exhibits the s,p,d,f shells characteristic of single atoms, so they are often referred to as "artificial atoms."
The NRL researchers monitor the shell population and spin polarization ...
... due to the spin of the electron. The study reveals that the behavior of quantum dots (sort of artificial atoms created with semiconductor materials) is different from that of natural atoms in similar ...
... of optical materials that essentially constitute a new form of matter that can be considered as "artificial atoms." Like atoms, they have discrete optical energy spectra that are tunable over a wide ...
... conventional computers. But following the counterintuitive laws of quantum mechanics, the scientists can also place these artificial atoms in "superpositions" of quantum states-both "off" and "on" at ...

He explained that in this work they operated a quantum circuit as a more complicated artificial atom with up to five energy levels. The generic term for such a system is "qudit," ...
