It is an open challenge to implement a coherent quantum annealer with fully programmable all-to-all connectivity. Here the authors present a scheme based on enhanced Rydberg-dressed interactions between neutral atoms in an optical lattice which is pr

We demonstrate the ability to excite atoms at well-defined, programmable locations in a magneto-optical trap, either to the continuum (ionization), or to a Rydberg state. To this end, excitation laser light is shaped into arbitrary intensity patterns

We measure the excitation spectrum of a stable dipolar Bose--Einstein condensate over a wide momentum-range via Bragg spectroscopy. We precisely control the relative strength, $\epsilon_{\rm dd}$, of the dipolar to the contact interactions and observ

We study the spectrum of elementary excitations of a dipolar Bose gas in a three-dimensional anisotropic trap across the superfluid-supersolid phase transition. Theoretically, we show that, when entering the supersolid phase, two distinct excitation

We demonstrate precise control of charged particle bunch shape with a cold atom electron and ion source to create bunches with linear and, therefore, reversible Coulomb expansion. Using ultracold charged particles enables detailed observation of spac

There is a significant ongoing effort in realizing quantum annealing with different physical platforms. The challenge is to achieve a fully programmable quantum device featuring coherent adiabatic quantum dynamics. Here we show that combining the wel

We devise a cold-atom approach to realizing a broad range of bilinear quantum magnets. Our scheme is based on off-resonant single-photon excitation of Rydberg $P$ states (Rydberg dressing), whose strong interactions are shown to yield controllable $X

We create ultracold ion bunches via precisely shaped photoionisation of laser cooled atoms that exhibit linear Coulomb self-field expansion, smaller emittance growth and hence improved brightness under transverse focusing in comparison to standard Ga
