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
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

An important aspect for practical quantum computation is the ability to precisely manipulate the fundamental unit of quantum information, the qubit, through coupling the qubit to a drive signal.
Dynamics of quantum systems driven by time-varying Hamiltonians: Solution for the Bloch-Siegert Hamiltonian and applications to NMR
Comprehending the dynamical behaviour of quantum systems driven by time-varying Hamiltonians is particularly difficult. Systems with as little as two energy levels are not yet fully understood as the
Floquet analysis of a quantum system with modulated periodic driving
We consider a quantum system periodically driven with a strength which varies slowly on the scale of the driving period. The analysis is based on a general formulation of the Floquet theory relying
Floquet theory for short laser pulses
Abstract:We develop adiabatic perturbation theory for quantum systems responding to short laser pulses, with or without a frequency chirp. Our approach rests on lifting the time-dependent Schrödinger

We give a general overview of the high-frequency regime in periodically driven systems and identify three distinct classes of driving protocols in which the infinite-frequency Floquet Hamiltonian is
Introduction of the Floquet-Magnus expansion in solid-state nuclear magnetic resonance spectroscopy.
In this article, we present an alternative expansion scheme called Floquet-Magnus expansion (FME) used to solve a time-dependent linear differential equation which is a central problem in quantum
Simple pulses for elimination of leakage in weakly nonlinear qubits.
TLDR
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.
On the exponential solution of differential equations for a linear operator
The present investigation was stimulated by a recent paper of K. 0. Friedrichs 113, who arrived at some purely algebraic problems in connection with the theory of linear operators in quantum
