- Abstract summary: We study ARP in the simple setting of a two-level system subject to sinusoidal fluctuations on the energy level separation.
We find that it is predominantly affected by resonant coupling when the detuning matches the frequency of the noise.
We present intuitive principles for when ARP becomes inefficient within this model, and provide a sufficient condition for the population transfer to be above an arbitrary threshold.

- Abstract: Adiabatic Rapid Passage (ARP) is a powerful technique for efficient transfer
of population between quantum states. In the lab, the efficiency of ARP is
often limited by noise on either the energies of the states or the frequency of
the driving field. We study ARP in the simple setting of a two-level system
subject to sinusoidal fluctuations on the energy level separation by
numerically solving the optical Bloch equations in the absence of damping. We
investigate the dependence of the efficiency of population transfer on the
frequency and amplitude of the perturbation, and find that it is predominantly
affected by resonant coupling when the detuning matches the frequency of the
noise. We present intuitive principles for when ARP becomes inefficient within
this model, and provide a sufficient condition for the population transfer to
be above an arbitrary threshold.

We re-examine a scheme originally intended to remove the effects of static Doppler broadening from an ensemble of non-interacting two-level systems (qubits)
We demonstrate that this scheme is far more powerful and can also protect a single (or even an ensemble) qubit's energy levels from noise which depends on both time and space.

Recently, we have found that in open quantum systems, applying a strong drive can give rise to significant drive-induced dissipation (DID)
Here, we investigate the effect of DID on the performance of ARP that is implemented using a linearly chirped pulse on a two-level system.
We show that beyond a threshold value of the drive amplitude, the transfer probability is reduced because of DID.
