Open-system dynamics of Floquet-engineered state transfer

Quantify the dissipative and non-Markovian dynamics of the Floquet-engineered multi-excitation state-transfer protocol by performing a comprehensive open-system simulation, such as one based on a Lindblad master equation.

Background

The paper evaluates decoherence primarily through a timescale comparison between the gate durations and the estimated relaxation and dephasing times of superconducting transmon devices. Although the resulting gate times are much shorter than the quoted coherence times, this comparison does not explicitly model dissipative evolution during the driven protocol.

The authors identify a comprehensive open-system simulation as necessary to quantify the effects of dissipation and possible non-Markovian dynamics. Such an analysis would determine whether the timescale-based estimate accurately captures the performance of the three targeted double-excitation transfer processes under realistic environmental noise.

References

This order-of-magnitude estimate suggests that environmental decay may not be the main limiting factor during a single stroboscopic cycle; however, a comprehensive open-system simulation (e.g., via the Lindblad master equation) remains to be performed to fully quantify dissipative and non-Markovian dynamics.
