Single-atom cooling by superfluid immersion: A nondestructive method for qubits
Physical Review A - Atomic, Molecular, and Optical Physics 69:2 (2004) 223061-2230616
Abstract:
A scheme to cool the motional state of neutral atoms confined in sites of an optical lattice by immersing the system in a superfluid was analyzed. It was shown that the motion of the atoms is damped by the generation of excitations in the superfluid, and under appropriate conditions the internal state of the atom remains unchanged. It was found that the scheme can be used to cool atoms used to encode a series of entangle qubits nondestructively. The rate of cooling to the ground state was found to be sufficiently large to be useful in experiments, within realizable parameter ranges.Defect-Suppressed Atomic Crystals in an Optical Lattice
