Aspects concerning the structure and behaviours of individual networks have been studied intensely in the past decade, but the exploration of interdependent systems in the context of complex networks has started only recently. This article reviews a general framework for modelling the percolation properties of interacting networks and the first results drawn from its study.

In recent years, progress has been made towards using cold atomic gases to study the role of disorder in many-body systems. This line of research might offer the key to solving open questions in solid-state physics, but should also provide a new outlook on disordered systems in its own right.

Quantum Darwinism describes the proliferation, in the environment, of multiple records of selected states of a quantum system — an approach that has resulted in considerable progress towards a solution of the quantum measurement problem.

So-called one-way schemes have emerged as a powerful model to describe and implement quantum computation. This article reviews recent progress, highlights connections to other areas of physics and discusses future directions.

Fluorophores are quantum objects that blink intermittently and whose dark states exist practically ‘forever’—on quantum-mechanical scales, that is. Although there is no accepted theory, there has been plenty of theoretical progress.
