PASQuanS2.1: Programmable atomic large-scale quantum simulation
Funding program for the development of programmable quantum simulators. Regarding the development of optical-lattice quantum simulators, the goal is to increase the programmabiliy, stability and size of current experimental platforms and to identify pathways towards demonstrating practical quantum advantage with analog quantum simulators. On the technological side, we are going to develop new experimental techniques in order to increase the fidelity of the initial-state preparation, enhance the data rate, achieve local control over tunnel couplings and improve the precision of applied local potentials.

DYNAMITE: Next Generation Quantum Simulators: From Dynamical Gauge Fields to Lattice Gauge Theory
Quantum Simulators can address and deepen our understanding of complex quantum many-body systems with applications ranging from condensed matter physics to nuclear physics, high energy physics and material science. Within this projects, we will develop novel methods for the realization of lattice gauge theories using present-day capabilities of cold-atom quantum simulators. Starting with implementations of Abelian gauge theories we will work towards the realization of more complex non-Abelian lattice gauge theories.

Munich Quantum Valley: Trapped Atom Quantum Computer (TAQC)
Neutral atoms trapped in optical lattices are a promising quantum-computing platform. Its main advantage is the potential of scaling to larger numbers of qubits already in the coming years. In this approach, qubits are encoded in individual addressable atoms cooled and trapped in an optical potential which is generated by crossed laser beams. Quantum gates can be realized by coupling to highly excited Rydberg states, whose strong, long-range interactions allow for entangling two or more atoms in the system. The single qubits can be addressed and coherently manipulated through local laser pulses. Within this project we are working towards realizing a first-generation neutral-atom quantum computing platform with ultracold ytterbium atoms.

MCQST: Munich Center for Quantum Science and Technology
The cluster of excellence MCQST comprises seven research units within disciplines such as physics, mathematics, computer science, electrical engineering, material science, and chemistry, covering all areas of Quantum Science and Technology (QST) from basic research to applications. We are contributing to two research units: RU-B on Quantum Simulation and RU-G on Explorative Research Directions. One of the exciting goals of RU-G is to connect concepts from quantum simulation of many-body systems and quantum information to other research areas ranging from quantum chemistry to cosmology and high-energy physics.

FermiQP: Joint Project on Fermion Quantum Processors
This project aims at realizing a new and scalable hybrid platform for analogue quantum simulation and digital quantum computing with ultracold fermion, thus combining the advantages of both concepts in one machine. Within this project we are developing new techniques for improving the coherence time, data rate and initial-state fidelity, which will boost both analogue and digital applications of this hybrid platform.

LaGaTYb: Exploring lattice gauge theories with fermionic Ytterbium atoms
Gauge theories establish a connection between seemingly different physical areas, ranging from high-energy to condensed matter physics. Very often gauge theories are difficult to study theoretically in particular in the strongly-interacting regime, where perturbative methods are not reliable. This motivates the search for alternative approaches using quantum simulation. Ultracold atoms in optical lattices have proven powerful in studying important condensed matter models and intriguing results have been achieved in simulating static background gauge fields. This establishes a link to more general gauge theories, yet these are out-of-reach due to complex requirements e.g. regarding the implementation of gauge and matter field degrees of freedom. Within this project, we are going to develop a novel experimental platform that combines two unique features: precise local control and scalability to generate advanced optical lattices with locally controllable tunnel couplings. It will facilitate the implementation of a broad class of gauge theories, so-called quantum link models, with fermionic atoms, where matter and gauge fields are interpreted as different lattice sites.

FOR2414: Artificial Gauge Fields and Interacting Topological Phases in Ultracold Atoms
Gauge fields can dramatically change the properties of a material. A seminal example is the one of electrons subjected to an external magnetic field, leading to the quantum Hall effect. Here, a variety of exotic quantum phenomena arise, where topology plays a fundamental role: from the existence of topological invariants and topologically protected edge currents to the emergence of quasiparticles with exotic braiding statistics. These fascinating effects are at the focus of current theoretical and experimental research. Within this Research Unit we are developing experimental techniques for quantum simulation of topological phases of matter including paradigmatic condensed matter Hamilonians, such as the Hofstadter and Haldane model. Moreover, we are investigating genuine out-of-equilibrium phases without any static analogue, so-called anomalous Floquet topological systems.
