MAIN TALK
SPEAKER: Han Cai
TITLE: Synthetic magnetic field in thermal atomic vapor
ABSTRACT:
Intense effort is currently devoted to the creation of gauge fields for electrically neutral atoms. I will introduce some recent works in generating a cold-atom lattice pierced by a uniform magnetic field. Specially, I will describe the method to extend a one-dimensioanl optical lattice into the "dimension" provided by the internal atomic degrees of freedom, yielding a synthetic two-dimensional optical lattice. However, currently synthetic gauge fields can only be observed in ultracold atomic lattice. Our simulation shows that It is possible see the effect in thermal vapor

TITLE: Automated Search for new Quantum Experiments
ABSTRACT:
We report the computer algorithm MELVIN which is able to find new experimental implementations for the creation and manipulation of complex quantum states. The results range from the first implementation of a GHZ state, to a vast variety of experiments for asymmetrically entangled quantum states. The discovered experiments extensively use unfamiliar and asymmetric techniques which are challenging to understand intuitively. Additionally MELVIN autonomously learns from solutions for simpler systems, which significantly speeds up the discovery rate of more complex experiments. The ability to automate the design of a quantum experiment allows the physical realization of quantum states previously thought of only on paper.
