Understanding strongly coupled gauge theories is a fundamental challenge of physics, with dramatic

implications both for high energy and condensed matter. Doing it with a quantum simulator is a

formidable test for quantum simulation. Here we show that by exploiting electromagnetic duality, we

can create the Rokhsar-Kivelson Hamiltonian –a 2D U(1) lattice gauge theory that describes quantum

dimers- in running Rydberg experiments by exploiting Rydberg blockade in a novel fashion. Quantum

The problem to determine the classical and quantum optimal strategies for quantum games rely at the heart of quantum non-locality and its applications to quantum technologies. These optimal strategies are hard to find even in relatively simple scenarios. In this work, we establish a one-to-one connection existing between the problem of calculating the optimal classical strategy of a game and a well-studied problem in mathematics some decades ago, namely to calculate the excess of a matrix.

The Kitaev honeycomb model is a paradigm of exactly-solvable models, showing non-trivial physical properties such as topological quantum order, abelian and non-abelian anyons, and chirality. Its solution is one of the most beautiful examples of the interplay of different mathematical techniques in condensed matter physics. In this talk I will show how to derive a tensor network (TN) description of the eigenstates of this spin-1/2 model in the thermodynamic limit, and in particular for its ground state.
