Programmable quantum simulators and quantum computers are opening unprecedented
opportunities for exploring and exploiting the properties of highly entangled complex …

Quantum simulators are a promising technology on the spectrum of quantum devices from
specialized quantum experiments to universal quantum computers. These quantum devices …

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 …

The complexity of quantum states has become a key quantity of interest across various
subfields of physics, from quantum computing to the theory of black holes. The evolution of …

We show that out-of-time-order correlators (OTOCs) constitute a probe for local-operator
entanglement (LOE). There is strong evidence that a volumetric growth of LOE is a faithful …

Interactions between atoms and light in optical cavities provide a means of investigating
collective (many-body) quantum physics in controlled environments. Such ensembles of …

This tutorial article introduces the physics of quantum information scrambling in quantum
many-body systems. The goals are to understand how to precisely quantify the spreading of …

We study quantum information scrambling in a random unitary circuit that exchanges qubits
with an environment at a rate p. As a result, initially localized quantum information not only …

Interacting many-body quantum systems show a rich array of physical phenomena and
dynamical properties, but are notoriously difficult to study: they are analytically challenging …

Thermodynamic systems typically conserve quantities (known as charges) such as energy
and particle number. The charges are often assumed implicitly to commute with each other …
