Description

The real-time phenomenology of interacting quarks and gluons remains largely beyond the reach of computational techniques based on stochastic methods due to the fermionic sign problem. As a consequence, simulations of parton dynamics—particularly their transformation into final-state hadrons through fragmentation and hadronisation—are currently not feasible with these approaches.

In this work, we present an algorithm to compute fragmentation functions on quantum computers and provide proof-of-concept simulations performed on classical hardware. Along the way, we introduce several strategies to address the challenges of the problem, all based on a codification paradigm in which particles and their internal degrees of freedom are treated as the fundamental objects.
