For a linearly driven quantum two-level system, or qubit, sets of stroboscropic points along the cycloidal-like trajectory in the rotating frame can be approximated using the exact rotating wave approximation introduced in arXiv:1807.02858. That work introduces an effective Hamiltonian series $\mathcal H_{\text{eff}}$ generating smoothed qubit trajectories; this series has been obtained using a combination of a Magnus expansion and a Taylor series, a Magnus-Taylor expansion. Since, however…

Flow-equation approach to quantum systems driven by an amplitude-modulated time-periodic force
• Physics
Physical Review A

We apply the method of flow equations to describe quantum systems subject to a time-periodic drive with a time-dependent envelope. The driven Hamiltonian is expressed in terms of its constituent

This work provides an easy to implement analytic formula that inhibits leakage from any single-control analog or pixelated pulse, based on adding a second control that is proportional to the time derivative of the first.
