DESCRIPTION:Speakers: Naman Jain (Max Planck Institute of Quantum Optics\,
  Garching\, Germany)\n\nExercising precise control over quantum systems co
 uld offer a complementary route to many-body physics: rather than inferrin
 g microscopic mechanisms from collective behaviour\, we can prepare a syst
 em with a known microscopic structure and study how its properties emerge.
  Realizing this experimentally requires control over all the relevant degr
 ees of freedom of an atomic ensemble – including particle number\, spin\
 , motional state\, and position.In this talk\, I will present a new-genera
 tion fermionic quantum gas microscope platform that achieves these objecti
 ves\, enabling the prospects of assembling quantum systems from the bottom
 -up using lithium-6. Specifically\, I will talk about our recent results d
 emonstrating high-fidelity preparation of programmable spin and charge pat
 terns across an 8x8 two-dimensional optical tweezer array of up to 128 ato
 ms\, deterministically in the motional ground state. This is complemented 
 by a single-exposure imaging scheme that provides spin-\, site- and densit
 y-resolved detection of these atomic ensembles at microsecond timescales w
 ith high fidelity. I will discuss how these capabilities of programmable i
 nitialization and ultrafast detection\, would provide a unique vantage poi
 nt for the exploration of nonequilibrium many-body physics in itinerant sy
 stems. I will also briefly present our recent results from tunnel-coupling
  these product states prepared in tweezers\, where coherent evolution offe
 rs a first step towards analog–digital hybrid approaches to studying qua
 ntum dynamics and realizing fermionic quantum processing architectures.\n\
