Exploring the physics of quantum measurement with superconducting circuits

2 décembre @ 14 h 00 min - 16 h 00 min

Séminaire de Benjamin Huard — groupe circuit quantique de l’ENS Lyon —

When a quantum system is measured, it collapses onto a state that corresponds to the measurement outcome. This measurement backaction takes subtle forms if the system first interacts with an ancillary quantum system, which is then measured. Observing these phenomena requires detectors, which are able to extract most of the information leaking out of a quantum system. Superconducting circuits offer a testbed for these questions. In this talk, I will show how various forms of quantum measurement backaction can be observed in circuit quantum electrodynamics (c-QED) experiments. We will also discuss how these experiments shed light on the recent field of thermodynamics of quantum information.
