Abstract
A trap for quantum particles, e.g., cesium atoms, is formed using electromagnetic radiation (EMR) of different wavelengths (concurrently and/or at different times). “Red-detuned” EMR, having a trap wavelength longer than a resonant wavelength for a quantum particle is “attracting” and, so, can be used to form the array trap while loading atoms into the array trap. “Blue-detuned” EMR, having a trap wavelength shorter than the resonant wavelength can repel atoms into dark areas away from the EMR peaks so that the atoms are not disturbed by interference carried by the EMR; accordingly, the blue-detuned EMR is used to form the array trap during quantum-circuit execution. Red and blue detuned EMR are used together to form deeper traps that can be used to detect vacant atom sites. Other combinations of trap wavelengths can also be used.
