Non-perturbative QC D phenomenology is typically investigated using Monte Carlomethods that re ly on averaging over static bosonic field configurations. However\,these m ethods break down in the presence of a finite baryon density (chemicalpote ntial) or when simulating real-time dynamics.

Such situations ar ise\, for instance\,in the fragmentation of quarks into hadrons or in the physics of neutron-star cores.Quantum computing offers promising new avenu es to address these difficulties — ifscalable architectures become avail able — but they face intrinsic complexities such usthe trade-off between a dense encoding of the relevant degrees of freedom and anefficient decom position of the resulting unitary transformations.

In this talk\ , wepresent a novel register-based encoding of canonically quantized QCD i n the timeaxial / Weyl gauge. We detail the implementation of key Hamilton ian terms anddemonstrate small-scale simulations that provide a preliminar y assessment of thecomputational time and memory resources required.
