报告摘要:

Quantum simulation of HEP has seen remarkable growth in recent years. Nevertheless, there is a continuous need for advancements in the overall simulation framework. I will discuss a specific foundational element - digitization, a crucial method for encoding field variables into qubits. This is particularly relevant for gauge theories with local symmetry and field variables of infinite dimension. During the talk, I will explore the connection between gauge theory digitization methods and approximate error correction codes, present the existence of error thresholds below which gauge-redundant digitizations combined with error correction has better fidelity than the gauge-fixed digitization.
