Abstract:

Neutral atoms are natural candidates as the keepers of quantum information given their weak coupling to the environment and the rapid advances in laser cooling and trapping technology. Many tools for building a rudimentary quantum computer are currently or nearly in place state preparation through optical pumping, coherent control through laser/rf spectroscopy, measurement through monitored quantum jumps. In order to make progress towards the ultimate goal, we must focus attention on laboratory development of these control tools, must crucially two-qubit quantum logic gates. For atoms, this is effectively the problem of coherent control of a dimer. This is the newest ingredient beyond that common employed in atomic clocks and analogous systems. Optical lattices provide an excellent arena in which to begin implementing these building blocks, with promise of scalability and parallelism necessary for ultimate fault-tolerant operation.
