| Abstract | We report laser-cooling of a single Be ion held in a rf (Paul) ion trap to where it occupies 9 + the quantum-mechanical ground state of motion. With the use of resolved-sideband stimulatedRaman cooling, the zero-point of motion is achieved 98% of the time in 1-D and 92% of the time in 3-D. Cooling to the zero-point energy appears to be a crucial prerequisite for future experiments such as the realization of simple quantum logic gates applicable to quantum computation. PACS numbers: 32.80.Pj, 42.50.Vk, 42.65.Dr 2 Dramatic progress in the field of atomic laser-cooling has provided cooling of free or weaklybound atoms to temperatures near the Doppler cooling limit [1], near the photon recoil limit [2], and more recently below the photon recoil limit [3],[4]. For a tightly bound atom, a more natural energy scale is given by the quantized vibrational level n, where the energy is E = ST (n+½) for an atom v confined in a harmonic potential of frequency T . In this case, the fundamental ... |
