Abstract: From bio-physics to quantum simulators, many fields depend on sub-diffraction imaging of multiple point sources.

Abstract: ‘Experiments whose data are processed using a computational model are often plagued by unc

Our group studies chemical reactions of ultracold Rb atoms in a state-to-state
resolved fashion, where we prepare reactants in well defined quantum states and
measure the quantum states of the molecular products. In particular, we focus on
three-body recombination where three atoms collide, forming a diatomic molecule.
The  third   atom carries  away  part  of  the  binding   energy.   We are  currently
investigating methods to gain control over this chemical reaction. By making use of

Abstract: In this talk, I’ll discuss a new framework to simulate the open dynamics of many-boson quantum systems. We use a superposition of squeezed-displaced states as a non-Gaussian state (NGS) ansatz. It is not restricted to a low excitation subspace, and can describe a variety of interesting quantum states (eg. squeezed cat states).

Abstract:

Neutral atoms have emerged in recent years as a leading qubit candidate for quantum computing. Atom interferometers, meanwhile, provide precise measurements of very weak gravitational forces. Both of these applications use optical fields to write-in / read-out information, as well as to trap and manipulate the atoms. Optical resonators have been used to enhance such atom-photon interactions, constituting the field of cavity quantum electrodynamics (QED).

Abstract: Trapped ion systems are a leading platform for quantum information processing, but they are currently limited to 1D and 2D arrays, which imposes restrictions on both their scalability and their range of applications.
