Abstract

Recent progress in nano-meter structure and measurements is going to provide us the freedom to domesticate fast correlations between atoms in an ensemble, manifesting them at macroscopic level. Here, we show a possibility to generate an electron coherence within an atomic ensemble, via the quantum resonance due to parity inheriting dynamic dipole-dipole interaction. We built up a realistic Hamiltonian having a combinatorial probability factors for the dynamic dipole-dipole quantum resonance. This leads to the precise simulation of the process that will actually occur in nature obeying the energy conservation law. We also show a preliminary experimental data suggestive of the dynamic dipole-dipole mode. These results lead to our proposal of solid state room temperature quantum computer, e.g. by a solid state qubit system of arrayed quantum dots designed to resist against phase errors as well as bit errors.
