Superconducting Devices for Quantum Optics and Quantum Simulations

Superconducting devices have gained increasing attention over the past decade as powerful platforms for quantum optics as well as quantum information processing. In particular, superconducting circuits based on non-linear elements, such as Josephson junctions and high kinetic inductance materials, are opening up a new regime for quantum optics experiments at microwave frequencies and quantum analog simulators.

The workshop "Superconducting Quantum Devices for Quantum Optics and Quantum Simulations" aims to address the recent developments of the field of microwave quantum optics for circuit-QED experiments, quantum simulation approaches and novel detection schemes based on superconducting circuits.

This workshop will bring together young and senior researchers in the field, as well as international theoreticians and experimentalists to foster exchange and spark ideas for new projects and collaborations, advancing the field of superconducting quantum devices.
