Quantum Control of Trapped Atomic Ions

David J. Wineland

Published Jan 1, 2013• 0 citations
Publisher

Abstract

Precise control of quantum systems currently occupies many labs throughout the world, with recent interest focusing on quantum information. This talk will focus on quantum-state manipulation in the context of trapped ions, one example of similar work that is being carried out with many other AMO and condensed matter systems.

Experimental quantum simulations of many-body physics with trapped ions

Ch Schneider, Diego Porras, Tobias Schaetz

Direct experimental access to some of the most intriguing quantum phenomena is not granted due to the lack of precise control of the relevant parameters in their naturally intricate environment. Their simulation on conventional computers is impossible, since quantum behaviour arising with superposition states or entanglement is not efficiently translatable into the classical language. However, one could gain deeper insight into complex quantum dynamics by experimentally simulating the quantum behaviour of interest in another quantum system, where the relevant parameters and interactions can be controlled and robust effects detected sufficiently well. Systems of trapped ions provide unique control of both the internal (electronic) and external (motional) degrees of freedom. The mutual Coulomb interaction between the ions allows for large interaction strengths at comparatively large mutual ion distances enabling individual control and readout. Systems of trapped ions therefore exhibit a prominent system in several physical disciplines, for example, quantum information processing or metrology. Here, we will give an overview of different trapping techniques of ions as well as implementations for coherent manipulation of their quantum states and discuss the related theoretical basics. We then report on the experimental and theoretical progress in simulating quantum many-body physics with trapped ions and present current approaches for scaling up to more ions and more-dimensional systems.

Applications of photonics in trapped ion quantum computing

Crystal Senko

The quest to engineer quantum computers of a useful scope faces many challenges that will require continued investigation of the physics underlying the devices. In this talk, I focus on trapped ion quantum computing. I discuss several recent advances my research group has contributed regarding optical control of Ba+ ions for quantum information processing, including multi-level qudit control and novel all-optical loading techniques, and provide a brief outlook on how photonic technologies can enable further progress in this field.

Molecular-ion quantum technologies

Mudit Sinhal, Stefan Willitsch

Quantum-logic techniques for state preparation, manipulation, and non-destructive interrogation are increasingly being adopted for experiments on single molecular ions confined in traps. The ability to control molecular ions on the quantum level via a co-trapped atomic ion offers intriguing possibilities for new experiments in the realms of precision spectroscopy, quantum information processing, cold chemistry, and quantum technologies with molecules. The present article gives an overview of the basic experimental methods, recent developments and prospects in this field.

10 Hybrid quantum systems of atoms and ions

Christoph Zipkes, Lothar Ratschbacher, Stefan Palzer +1 more

In recent years, ultracold atoms have emerged as an exceptionally controllable experimental system to investigate fundamental physics, ranging from quantum information science to simulations of condensed matter models. Here we go one step further and explore how cold atoms can be combined with other quantum systems to create new quantum hybrids with tailored properties. Coupling atomic quantum many-body states to an independently controllable single-particle gives access to a wealth of novel physics and to completely new detection and manipulation techniques. We report on recent experiments in which we have for the first time deterministically placed a single ion into an atomic Bose Einstein condensate. A trapped ion, which currently constitutes the most pristine single particle quantum system, can be observed and manipulated at the single particle level. In this single-particle/many-body composite quantum system we show sympathetic cooling of the ion and observe chemical reactions of single particles in situ.
