A special laser configuration designs a quantum interference that can cool to vanishing phonon occupation up to first order in the Lamb-Dicke parameter expansion. It hence eliminates the blue sideband in addition to the carrier transition, thus excluding any heating process involving up to one-phonon dynamics. It is applicable to trapped ions, atoms or cantilevers. The underlying combined action of two cooling schemes makes the proposal very stable under fluctuations of the physical parameters such as laser intensity or detuning, making it a viable candidate for experimental implementation. Furthermore, it performs faster than existing ground state cooling schemes, overcoming one of the limitations of current quantum information processing implementations.
