We quantitatively assess the energetic cost of several well-known control protocols that achieve a finite time adiabatic dynamics, namely counterdiabatic and local counterdiabatic driving, optimal control, and inverse engineering. By employing a cost measure based on the norm of the total driving Hamiltonian, we show that a hierarchy of costs emerges that is dependent on the protocol duration. As case studies we explore the Landau–Zener model, the quantum harmonic oscillator, and the Jaynes…

Quantum State Engineering by Shortcuts to Adiabaticity in Interacting Spin-Boson Systems.

This work presents a fast and robust framework to prepare nonclassical states of a bosonic mode exploiting a coherent exchange of excitations with a two-level system ruled by a Jaynes-Cummings interaction mechanism and shows how to obtain a class of photon-shifted states where the vacuum population is removed.

Trade-Off Between Speed and Cost in Shortcuts to Adiabaticity.

The speed with which a quantum system can be driven when employing transitionless quantum driving is studied to establish a rigorous link between this speed, the quantum speed limit, and the (energetic) cost of implementing such a shortcut to adiabaticity.

Driving at the quantum speed limit: optimal control of a two-level system.

A remarkably simple result is derived for the minimal time Tmin required to drive a general initial state to a final target state by a Landau-Zener-type Hamiltonian or, equivalently, by

There are a number of tasks in quantum information science that exploit non-transitional adiabatic dynamics. Such a dynamics is bounded by the adiabatic theorem, which naturally imposes a speed limit

Thermodynamic cost for classical counterdiabatic driving.

It is shown that a universal trade-off between speed and cost for CD also exists in the classical case, and a new complementary definition of cost is provided, which is of particular relevance for cases where the average excess work vanishes.
