Any physical process can be represented as a quantum channel mapping an initial state to a
final state. Hence it can be characterized from the point of view of communication theory, ie …

A fundamental distinction between many-body quantum states are those with short-and long-
range entanglement (SRE and LRE). The latter cannot be created by finite-depth circuits …

We consider the preparation of matrix product states (MPS) on quantum devices via
quantum circuits of local gates. We first prove that faithfully preparing translation-invariant …

In the field of monitored quantum circuits, it has remained an open question whether finite-
time protocols for preparing long-range entangled states lead to phases of matter that are …

Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

Measurements allow efficient preparation of interesting quantum many-body states with long-
range entanglement, conditioned on additional transformations based on measurement …

We review recent developments in the physics of ultracold atomic and molecular gases in
optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard …

The strongest adversary in quantum information science is decoherence, which arises
owing to the coupling of a system with its environment. The induced dissipation tends to …

We discuss the characterization and stability of the Haldane phase in integer spin chains on
the basis of simple, physical arguments. We find that an odd-S Haldane phase is a …

This work gives a detailed investigation of matrix product state (MPS) representations for
pure multipartite quantum states. We determine the freedom in representations with and …
