From Analog to Computational Quantum Simulation with Neutral Atoms

Neutral-atom quantum simulators in optical lattices have rapidly evolved into some of the
most powerful near-term quantum devices for exploring the complex properties of
quantum many-body systems. Unlike universal quantum processors, these analog platforms
realize targeted Hamiltonians directly from the microscopic interactions between atoms.
State-of-the-art systems now operate with hundreds to thousands of individually
controllable atoms, enabling precise studies of strongly correlated quantum matter, both in
and out of equilibrium.
The system sizes and coherence times available in state-of-the-art experiments challenge
the most advanced classical computations. In this talk, I will focus on two emerging
directions: (i) integration of digital control operations for flexible state preparation and
readout; (ii) quantum simulation of topological phases of matter and large-scale twodimensional
lattice gauge theories. Together, these advances mark a transition from analog
to computational quantum simulation - where neutral-atom platforms not only emulate, but
begin to predict complex quantum phenomena and enable new discoveries.
