Laser spectroscopy : proceedings of the XVI International Conference, Palm Cove, Queensland, Australia, 13-18 July 2003

Peter Hannaford

This volume comprises a collection of invited and selected contributions presented at the 16th International Conference on Laser Spectroscopy in Palm Cove, Queensland, Australia, 13-18 July 2003. The papers report developments in laser spectroscopy and related areas including: new ultra-precise spectroscopic measurements based on optical frequency combs including tests of the stability of the fundamental constants; the first successful production of cold antihydrogen; the first realization of Bose-Einstein condensation in cesium and ytterbium; the behaviour of ultra-cold bosons and fermions in optical lattices; the production of ultra-cold cesium, helium and fermionic lithium molecules; the production and coherent transport of ultra-cold atoms in microtraps on the surface of chips; the implementation of one- and two-qubit quantum algorithms and experiments towards a scalable quantum computer based on trapped ions; and new medical applications of laser spectroscopy.

Generating nonlinearities from conditional linear operations, squeezing, and measurement for quantum computation and super-Heisenberg sensing

Mattias Johnsson, Pablo M. Poggi, Marco A. Rodríguez-García +2 more

Large bosonic or continuous variable nonlinearities can have numerous applications, ranging from the generation of cat states for quantum computation, through to quantum sensing where the sensitivity exceeds Heisenberg scaling in the resources.However, the generation of ultra-large nonlinearities has proved immensely challenging experimentally.We describe a novel protocol where one can effectively generate large Kerr-type nonlinearities via the conditional application of a linear operation on an optical mode by an ancilla mode, followed by a measurement of the ancilla and corrective operation on the probe mode.Our protocol can generate high-quality Schrödinger cat states useful for quantum computing and can be used to perform sensing of an unknown rotation or displacement in phase space, with super-Heisenberg scaling in the resources.We finally describe a potential experimental implementation using atomic ensembles interacting with optical modes via the Faraday effect.
