FCQO18 Summary

Over the past few days, IST Austria became a meeting point for quantum technology experts during the “Frontiers of Circuit QED and Optomechanics” (FCQO18) conference. The meeting with about 110 participants addressed a wide range of topics from reservoir engineering to hybrid quantum devices to quantum error correction (press release).


New circulator uses mechanics

Nonreciprocal circuit elements form an integral part of modern measurement and communication systems. Mathematically they require breaking of time-reversal symmetry, typically achieved using magnetic materials and more recently using the quantum Hall effect, parametric permittivity modulation or Josephson nonlinearities. We realized an in-situ reconfigurable, magnetic-free, on-chip circulator based on reservoir-engineered electromechanic interactions.
