Dynamical quantum phase transitions (DQPT) were proposed 10 years ago as singularities developing in time following a quantum quench in the return amplitude or the Loschmidt echo. They have close connection with the Fisher zeros of the partition function extended to imaginary temperatures (real time). Because the Loschmidt echo is hard to measure it is...

An exciting frontier in quantum information science is the creation and manipulation of quantum systems that are built and controlled quanta by quanta. In this context, there is active research worldwide to achieve strong and coherent coupling between light and matter as the building block of complex quantum systems. Despite the range of physical behaviours...

In quantum science we often simplify our analyses by treating quantum systems as two-level qubits, and by assuming that the decoherence events of two or more unentangled qubits are uncorrelated from each other. For example, both of these assumptions are central tenets of circuit-based quantum error correction protocols. However, in experiments these assumptions regularly break...

Understanding the behavior of strongly interacting electrons in solids under strong magnetic fields has been a paradigmatic goal of physics research. Ultracold alkaline-earth atoms (AEAs) loaded in optical lattices featuring a clean, isolated and controllable environment are emerging as powerful quantum simulators which can shed light into this challenging problem. A unique appeal of AEAs...

The field of circuit QED has emerged as a rich platform for both quantum computation and quantum simulation. Lattices of coplanar waveguide (CPW) resonators realize artificial photonic materials in the tight-binding limit. Combined with strong qubit-photon interactions, these systems can be used to study dynamical phase tranisitions, many-body phenomena, and spin models in driven-dissipative systems....
