Non-perturbative Q CD phenomenology is typically investigated using Monte Carlomethods that r ely on averaging over static bosonic field configurations. However\,these methods break down in the presence of a finite baryon density (chemicalpot ential) or when simulating real-time dynamics.

Such situations a rise\, for instance\,in the fragmentation of quarks into hadrons or in the physics of neutron-star cores.Quantum computing offers promising new aven ues to address these difficulties — ifscalable architectures become avai lable — but they face intrinsic complexities such usthe trade-off betwee n a dense encoding of the relevant degrees of freedom and anefficient deco mposition of the resulting unitary transformations.

In this talk \, wepresent a novel register-based encoding of canonically quantized QCD in the timeaxial / Weyl gauge. We detail the implementation of key Hamilto nian terms anddemonstrate small-scale simulations that provide a prelimina ry assessment of thecomputational time and memory resources required.
