Quantum computers [1–4] are explicitly quantum mechanical systems that use phenomena
such as superposition and entanglement to perform computational tasks more efficiently …

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 present the implementation of optimal control into the open source simulation package
SIMPSON for development and optimization of nuclear magnetic resonance experiments for …

We consider a two-level quantum system prepared in an arbitrary initial state and relaxing to
a steady state due to the action of a Markovian dissipative channel. We study how optimal …

In this article we formulate frictionless atom cooling in harmonic traps as a time-optimal
control problem, permitting imaginary values of the trap frequency for transient time intervals …

The aim of this book is to provide an introduction to some representative nonrelativistic
quantum control problems and to their theoretical analysis and solution by modern …

Storing information in quantum mechanical degrees of freedom and processing it by unitary
transformation promises a new class of computers that can efficiently solve problems for …

One of the main theoretical challenges in quantum computing is the design of explicit
schemes that enable one to effectively factorize a given final unitary operator into a product …

In ion-pair catalysis, the last intermediate structures prior to the stereoselective transition
states are of special importance for predictive models due to the high isomerization barrier …

We consider a pair of coupled spins with Ising interaction in the z direction and study the
problem of generating efficiently the triplet Bell state. We initially analyze the transitionless …
