We present an overview of the quantitative theory of single-copy entanglement in finite-
dimensional quantum systems. In particular we emphasize the point of view that different …

We review the recent progress in theory and experiments with lateral triple quantum dots
with controlled electron numbers down to one electron in each dot. The theory covers …

The ability to assemble weakly interacting subsystems is a prerequisite for implementing
quantum information processing and generating controlled entanglement. In recent years …

We propose a one-step scheme to generate Greenberger-Horne-Zeilinger (GHZ) states for
superconducting flux qubits or charge qubits in a circuit QED setup. The GHZ state can be …

We present two ready-to-use numerical algorithms to evaluate convex-roof extensions of
arbitrary pure-state entanglement monotones. Their implementation leaves the user merely …

The question whether a given quantum state is a ground or thermal state of a few-body
Hamiltonian can be used to characterize the complexity of the state and is important for …

We present a numerical strategy to efficiently estimate bipartite entanglement measures, and
in particular the entanglement of formation, for many-body quantum systems on a lattice. Our …

By applying the conjugate gradient method in the evaluation of three-qubit's three-tangle,
the genuine tripartite entanglement dynamics and transfer for a triple Jaynes-Cummings …

At the heart of the curious phenomenon of quantum entanglement lies the relation between
the whole and its parts. In my thesis, I explore different aspects of this theme in the …
