- Abstract: As noisy intermediate-scale quantum (NISQ) processors increase in size and
complexity, their use as general purpose quantum simulators will rely on
algorithms based on the Trotter-Suzuki expansion. We run quantum simulations on
a small, highly accurate quantum processor, and show how one can optimize
simulation accuracy by balancing algorithmic (Trotter) errors against native
errors specific to the quantum hardware at hand. We further study the interplay
between native errors, Trotter errors, and the emergence of chaos as seen in
measurements of a time averaged fidelity-out-of-time-ordered-correlator

We show that when the gate error is decreased by approximately an order of magnitude relative to typical modern values, higher-order Trotterization becomes advantageous.
This form of Trotterization yields a global minimum of the overall simulation error.

Quantum algorithms for quantum dynamics simulations are traditionally based on implementing a Trotter-approximation of the time-evolution operator.
variational quantum algorithms have become an indispensable alternative, enabling small-scale simulations on present-day hardware.
We show that, despite providing a clear reduction of quantum gate cost, the variational method in its current implementation is unlikely to lead to a quantum advantage.

Simulating quantum dynamics beyond the reach of classical computers is one of the main envisioned applications of quantum computers.
The approximation error of these algorithms is often poorly understood, even in the most basic cases, which are particularly relevant for experiments.
Recent studies have reported anomalously low approximation error with unexpected scaling in such cases, which they attribute to quantum interference between the errors from different steps of the algorithm.
Our method generalizes state-of-the-art error bounds without the technical caveats of prior studies, and elucidates how each part of the total error arises from the underlying quantum circuit.
