Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the
experimental investigation of ultracold gases made of highly magnetic atoms has …

The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

Quantum metrology is one of the most promising applications of quantum technologies. The
aim of this research field is the estimation of unknown parameters exploiting quantum …

Interactions govern the flow of information and the formation of correlations between
constituents of many-body quantum systems, dictating phases of matter found in nature and …

Quantum technologies exploit entanglement to revolutionize computing, measurements, and
communications. This has stimulated the research in different areas of physics to engineer …

Entanglement is an important resource for quantum technologies. There are many ways
quantum systems can be entangled, ranging from the two-qubit case to entanglement in …

We summarize important recent advances in quantum metrology, in connection to
experiments in cold gases, trapped cold atoms and photons. First we review simple …

The permutational invariance of identical two-level systems allows for an exponential
reduction in the computational resources required to study the Lindblad dynamics of …

We construct quantum error-correcting codes that embed a finite-dimensional code space in
the infinite-dimensional Hilbert space of rotational states of a rigid body. These codes, which …

Quantum simulation of spin models can provide insight into problems that are difficult or
impossible to study with classical computers. Trapped ions are an established platform for …
