Claude Shannon (1916-2001), with his 1948 seminal article "A mathematical Theory of Communication" setting the general rules of contemporary information theory, laid the mathematical foundations for a technical revolution that we are currently enjoying. With his further work he brought deep theoretical insights and contributions for the convergence of computing and communications. This joint initiative of Centro Internacional de Matemática and Instituto de Telecomunicações, in collaboration with Instituto Superior Técnico and other institutions, celebrates Shannon's legacy at the University of Lisbon on the occasion of his centenary.

Two quantum emitters, embedded in a linear waveguide, can relax towards bound states for resonant values of the interatomic distance. The stability of such states is studied, and their relevance for entanglement generation is analyzed.
We shall also discuss the role of quantum simulators. They are more focused than quantum computers, and easier to build. They can solve fundamental problems that are untractable by classical hardware. Like quantum computers, simulators simultaneously perform a number of computations by exploiting the superposition principle and entanglement. This is known as quantum parallelism and can lead to an exponential speedup of performance.
We consider the example of a discrete Abelian gauge theory, towards the realization of a quantum simulator for QED in one dimension. We analyze the role of the finiteness of the gauge fields and the properties of physical states, satisfying Gausss law.
