Abstract:

Trapped ions are a promising experimental platform for preparing large amounts of quantum entanglement, eventually on a scale large enough for quantum computing. The laser and ion-trap technologies which have been developed so far offer the opportunity to apply them to more specialized and potentially less demanding applications in the short term. In this colloquium I will introduce the experimental techniques of trapped-ion quantum information, and discuss one particular application, namely using trapped ions and tailored laser-induced forces between them to perform 'quantum simulations' of designer Hamiltonians. Arrays of ions are naturally adept at simulating networks of interacting spins, which can exhibit quantum magnetism analogous to familiar condensed matter models. The ultimate goal would be to reveal quantum fluctuations, correlations, and dynamics in a quantum magnet, all at the level of single atoms.

Refreshments will be served at 3:25 pm.
