The study of open quantum systems–microscopic systems exhibiting quantum coherence
that are coupled to their environment–has become increasingly important in the past years …

Laser-cooled and trapped atomic ions form an ideal standard for the simulation of interacting
quantum spin models. Effective spins are represented by appropriate internal energy levels …

The relationship between thermodynamics and statistical physics is valid in the
thermodynamic limit—when the number of particles becomes very large. Here we study …

Quantum heat engines (QHE) are thermal machines where the working substance is a
quantum object. In the extreme case, the working medium can be a single particle or a few …

We investigate the connection between quantum resources and extractable work in
quantum batteries. We demonstrate that quantum coherence in the battery or the battery …

In classical computational chemistry, the coupled-cluster ansatz is one of the most
commonly used ab initio methods, which is critically limited by its nonunitary nature. The …

Quantum entangled states can be very delicate and easily perturbed by their external
environment. This sensitivity can be harnessed in measurement technology to create a …

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

Thermodynamics at the nanoscale is known to differ significantly from its familiar
macroscopic counterpart: The possibility of state transitions is not determined by free energy …
