DESCRIPTION:Speakers: Tilman Esslinger (ETH\, Switzerland)\n\nThe idea of 
 quantum simulation is to get insights into physical phenomena by synthetic
 ally creating insanely controlled quantum many-body systems. In my talk\, 
 I will show how quantum simulations of entire devices provide insights int
 o the geometric dependency of superfluidity and will give a perspective on
  ab-initio engineering of quantum-correlations in optical lattices using h
 igh-fidelity gates.\nIn standard conductors\, resistance decreases with in
 creasing cross-section. However\, in low-dimensional superconductors and s
 uperfluids residual resistance arises from topological fluctuations of the
  order parameter manifesting as phase slips in one-dimensional and vortice
 s in two-dimensional systems. In a recent quantum simulation\, we addresse
 d the open question of how resistance and dissipation evolve as geometry i
 nterpolates between these two regimes\, observing a quantum resistance par
 adox of low-dimensional superfluids.\nCorrelations are fundamental to unde
 rstanding the functioning of quantum many-body systems\, such as the Fermi
 -Hubbard model. Using the concept of topological pumping and exploiting a 
 two-particle quantum holonomy\, we realized a large number of ultra-high f
 idelity quantum swap gates that operate in parallel. These gates facilitat
 e recent experiments focused on engineering complex many-body states in an
  optical lattice and extracting distant two-particle spin correlations.
