This talk is a general introduction to quantum annealing. It covers: - how does a quantum annealer work in theory and what can it be used for; - what are the theoretical and practical limitations; - how to solve problems on quantum annealers, in particular D-Wave quantum annealers as the one hosted by JSC; - the basic information about the architecture of D-Wave quantum annealers; - how to formulate an optimization problem as a QUBO or Ising problem; - different encoding strategies; - how to incorporate constraints; - how to embed a (logical) problem onto the given hardware graph (considering physical connectivity); - how to send a problem to the quantum annealer using D-Wave's Ocean SDK and how to interpret the response; Finally, some small examples are presented and the talk ends with a short hands-on exercise.

I will talk about the first experimental signatures of two-dimensional many-body false vacuum decay in a quantum material emerging from microscopic interactions. We used a programmable noisy superconducting quantum simulator with 2008 qubits in order to perform simulations corresponding to our specific experiment on quantum domain reconfiguration in a topical electronic crystal. We carefully chose a simulator with the same measured noise spectrum to ensure the fidelity of the model correspondence between the two systems, thereby presenting a realization of simulating real-world open quantum systems according to the original vision of Feynman.
