Abstract 

In this year 2025 we celebrate the 100'th anniversary of quantum science. Quantum mechanics appeared as a tool to explain fundamental problems, from the structure of atoms to the interaction of matter and light. In mid XX century quantum mechanics became the tool to explain semiconductors and lasers, technologies that revolutionized our lives. The XXI century marks an era of quantum technologies, in which quantum mechanics is no longer confined to the very small. The well known superconducting quantum computers created by Google or IBM are an example of how we can now create and control hundreds of quantum devices, implementing arbitrary unitary operations, simulating sophisticated strongly correlated models and surpassing the limits of what is classically computable. In this talk I will discuss a newer generation of devices, superconducting quantum networks, in which such processors are connected by long cables or tubes, over separations of tens of meters. These networks allow us to explore topics such as quantum communication and distributed quantum processing, but also are a unique platform to understand the foundations of quantum mechanics and how local realism can be ruled by simple, Bell-style correlation experiments.
