Multi-reference Quantum Davidson Algorithm for Quantum Dynamics

Noah Berthusen, Faisal Alam, Yu Zhang

Simulating quantum systems is one of the most promising tasks where quantum computing can potentially outperform classical computing. However, the robustness needed for reliable si…

Quantum dynamics simulations beyond the coherence time on NISQ hardware by variational Trotter compression

Noah F. Berthusen, Thaís V. Trevisan, Thomas Iadecola +1

We demonstrate a post-quench dynamics simulation of a Heisenberg model on present-day IBM quantum hardware that extends beyond the coherence time of the device. This is achieved us…
