Abstract: As universal quantum computers move from theoretical devices towards concrete
realizations, albeit still quite experimental, there is a lot of interest in
understanding whether outstanding problems in nuclear physics, like real-time
dynamics and bulk properties of nuclear matter, could be solved using these
machines. For these applications we need to represent in hardware quantum field
theories for both fermionic and bosonics degrees of freedom. Discretized fermionic
fields can be represented fully since they map naturally onto qbits. On the other
hand bosonic degrees of freedom--which even for discretized fields require an
infinite dimensional Hilbert space at each site--require a truncation. In this
talk I discuss two directions we investigated to address this problem: using
discrete subsets to represent gauge degrees of freedom, or truncations in a dual
space that that preserve the original symmetries of the theory. As test-cases
for these ideas we use pure-gauge QCD and the sigma-model.
