DESCRIPTION:Abstract:Quantum field theories at strong coupling\, as in Qua
 ntum Chromodynamics (QCD)\,require a non-perturbative approach. Lattice di
 scretizations and simulations providesuch an approach\, which has achieved
  remarkable success. This is the case\, forexample\, of QCD at zero chemic
 al potential. However\, in cases like at finite chemicalpotential or under
  real-time evolution\, the best techniques are still hindered by theso-cal
 led sign problems.The emergence of quantum simulators for gauge theories\,
 which aim to simulate these theories directly on quantum devices\, opens u
 p apromising new avenue for tackling these challenges. Rather than elimina
 ting the needfor classical computational approaches\, the latter becomes c
 rucial for validatingquantum simulators and as probes of quantum supremacy
 . This talk will delve intoboth classical and quantum approaches to tackli
 ng these problems. In particular\, wewill discuss the basic requirements n
 eeded for quantum simulating gauge theories\,how they call for new classic
 al approaches\, and how all of these open the door to theexploration of ne
 w physics. By bridging the gap between classical and quantumapproaches\, w
 e aim to advance our understanding of physics at a fundamental leveland pa
 ve the way for future advancements in simulating gauge theories.
