摘要: Optically induced entanglement is identified by the spectrum of phase-sensitive homodyne-detected coherent nonlinear optical response in a single gallium arsenide quantum dot. The electron-hole involves two magneto-excitonic states differing transition energy and polarization. strong coupling needed for provided through Coulomb interaction involving electrons holes. result presents first step toward realization logic operations using or more dots.
