Engines are systems and devices that convert one form of energy into another, typically into
a more useful form that can perform work. In the classical setup, physical, chemical, and …

The chopped random basis (CRAB) ansatz for quantum optimal control has been proven to
be a versatile tool to enable quantum technology applications such as quantum computing …

It is control that turns scientific knowledge into useful technology: in physics and engineering
it provides a systematic way for driving a dynamical system from a given initial state into a …

We derive a Margolus-Levitin-type bound on the minimal evolution time of an arbitrarily
driven open quantum system. We express this quantum speed limit time in terms of the …

We propose an experimental scheme to realize a nanoheat engine with a single ion. An Otto
cycle may be implemented by confining the ion in a linear Paul trap with tapered geometry …

Quantum technologies rely on the ability to coherently transfer information encoded in
quantum states along quantum channels. Decoherence induced by the environment sets …

The advent of quantum devices, which exploit the two essential elements of quantum
physics, coherence and entanglement, has sparked renewed interest in the control of open …

We present a general method to efficiently design optimal control sequences for non-
Markovian open quantum systems, and illustrate it by optimizing the shape of a laser pulse …

Abstract The GRadient Ascent Pulse Engineering (GRAPE) method is widely used for
optimization in quantum control. GRAPE is gradient search method based on exact …

A pivotal task in quantum metrology, and quantum parameter estimation in general, is to
design schemes that achieve the highest precision with the given resources. Standard …
