The complex interaction among contemporary techno- and socio-economic processes has set the stage for the emergence of a cyber-physical universe, the novel landscape in which agents behave and interact, and which is centered on the fundamental role played by information and computation at all levels. In this paper, we weave into a single analysis the different threads that lead to (and characterize) the cyber-physical universe and outline a map of its building blocks and the complex dynamics at work in the new environment. The resulting description is used to assess how decision-making processes should evolve in order to be able to address the opportunities and challenges of the current era of deep and extended changes. The analysis offers an encompassing interpretative grid to understand and unpack patterns in the contemporary socio-technical systems that experience a fundamental informational turn; this can inform new research trajectories and help open up new areas for scientific inquiry.

In this paper, we extend the gap model of disability that supports digital equipment and cyber-physical situational variations. We explore an alternative approach to visualizing and understanding disability that takes into account the diversity of personal abilities, the diversity of digital equipment and equally important, the situation (environmental, psychological, and digital) in which the information system is used. The most important implications of this work are twofold.

Describing the properties of complex systems that evolve over time is a crucial requirement for monitoring and understanding them. Signal Temporal Logic (STL) is a framework that proved to be effective for this aim because it is expressive and allows state properties as human-readable formulae. Crafting STL formulae that fit a particular system is, however, a difficult task.

Universal quantum computation can be realised using both continuous-time and discrete-time quantum walks. We present a version based on single particle discrete-time quantum walk to realize multi-qubit computation tasks. The scalability of the scheme is demonstrated by using a set of walk operations on a closed lattice form to implement the universal set of quantum gates on multi-qubit system.

One of the core questions of quantum physics is how to reconcile the unitary evolution of quantum states, which is information-preserving and time-reversible, with evolution following the second law of thermodynamics, which, in general, is neither. The resolution to this paradox is to recognize that global unitary evolution of a multi-partite quantum state causes the state of local subsystems to evolve towards maximum-entropy states. In this work, we experimentally demonstrate this effect in linear quantum optics by simultaneously showing the convergence of local quantum states to a generalized Gibbs ensemble constituting a maximum-entropy state under precisely controlled conditions, while introducing an efficient certification method to demonstrate that the state retains global purity.
