Quantum computers promise to efficiently simulate quantum dynamics, a classically intractable task central to fields ranging from chemistry to high-energy physics. Quantum processors capable of high-fidelity mid-circuit measurement and qubit reuse enable a holographic technique that uses quantum tensor network states (qTNS), which efficiently compress quantum data, to simulate the evolution of infinitely-long, entangled initial states using a small number of qubits. In this poster, we discuss our recent benchmark of a holographic qTNS technique in a trapped ion quantum processor using 11 qubits to simulate an entangled state evolving under self-dual kicked Ising chain dynamics. We observe hallmarks of quantum chaos and light-cone propagation of correlations, and find excellent quantitative agreement with theoretical predictions for the infinite-size limit with minimal post-processing or error mitigation. These results show that qTNS methods, paired with state-of-the-art quantum processor capabilities, offer a viable route to practical quantum computational advantage on problems of direct interest to science and technology in the near term.
