This talk explores the exciting synergy between high-energy physics (HEP) and quantum technologies. We present results from our interdisciplinary collaboration, showcasing how quantum tools are revolutionizing our understanding of fundamental forces and vice versa.

  • Simulating the Strong Force: We demonstrate how tensor network algorithms, a powerful technique from quantum information, offer a novel approach to tackle real-time problems in lattice gauge theories (LGT), which are the cornerstone for studying the strong force (QCD). This paves the way for investigating out-of-equilibrium phenomena like dynamical string breaking, a key process in hadron formation.
  • Quantum Computing QCD: We delve into the realm of quantum simulation, exploring how quantum technologies can be harnessed to directly calculate "light-front parton correlators" - essential quantities in QCD that encode the non-perturbative (complex) behaviour of strong interactions. This opens doors to ab initio (from first principles) calculations, bypassing the limitations of traditional perturbative methods.
  •  Decoherence-robust Qubits: Finally, we explore the intriguing connection between anomalous symmetries and fault-tolerant qubits. We show how the concept of anomaly, a well-established principle in HEP, can explain the remarkable resilience of certain types of qubits (0-π qubits) to decoherence, a major obstacle in building large-scale quantum computers.
