Abstract:
Quantum processors with error mitigation are becoming powerful tools for exploring the non-equilibrium dynamics of many-body systems. Generic quantum dynamics often result in quickly vanishing correlation, making it difficult to resolve in present experiments. Here, we present a novel model employing perturbed mirror circuits to study complex dynamics in a quantum many-body system. These circuits retain large correlation while still challenging several classical simulation algorithms, including tensor-network and Pauli propagation methods. This positions the model as a realistic and physically motivated benchmark for the performance of quantum and classical simulation methods. In this talk, I will present details of our model, showcase classical benchmarking of the circuits, and discuss experimental results from IBM quantum processors.
