The technique of stimulated Raman adiabatic passage (STIRAP), which allows efficient and
selective population transfer between quantum states without suffering loss due to …

Identifying universal properties of nonequilibrium quantum states is a major challenge in
modern physics. A fascinating prediction is that classical hydrodynamics emerges …

We design, by invariant-based inverse engineering, resonant laser pulses to perform fast
population transfers in three-level systems. The laser intensities to improve the fidelity or to …

Considering the problem of the control of a two-state quantum system by an external field,
we establish a general and versatile method allowing the derivation of smooth pulses which …

Microwave trapped-ion quantum logic gates avoid spontaneous emission as a fundamental
source of decoherence. However, microwave two-qubit gates are still slower than laser …

The creation of composite quantum gates that implement quantum response functions U^(θ)
dependent on some parameter of interest θ is often more of an art than a science. Through …

We introduce universally robust sequences for dynamical decoupling, which simultaneously
compensate pulse imperfections and the detrimental effect of a dephasing environment to …

We introduce universal broadband composite pulse sequences for robust high-fidelity
population inversion in two-state quantum systems, which compensate deviations in any …

We devise a perturbation-immune version of Ramsey's method of separated oscillatory
fields. Spectroscopy of an atomic clock transition without compromising the clock's accuracy …

In this work, we put forward an approach of constructing the optimal composite pulse
sequence for robust population transfer in two-level systems. This approach is quite …
