"Building a quantum computer with neutral atoms"

I will describe our work towards making a quantum computer using ultra-cold atoms trapped in a 3D optical lattice. In particular, I will explain: how we change the quantum state of individual atoms, even in the middle of the array, without affecting the quantum states of other atoms; how we sort atoms by realizing a Maxwell's demon; and how we reliably detect the internal states of the atoms without losing any.


David Weiss' research involves experiments with laser-cooled atoms in optical lattices and other light traps. His group uses cold, trapped atoms to make precise measurements of fundamental constants and to test fundamental symmetries. They also use these atoms as model systems to address issues in atomic physics, condensed-matter physics, quantum mechanics, and statistical mechanics. David's group has three experimental apparatuses: one is devoted to the study of Bose-Einstein condensates in optical lattices, with an emphasis on 1D gases; one involves the development of a quantum computer using a 3D array of atoms; and one is working toward the measurement of the electron's electric dipole moment, using cold, trapped alkali atoms.
