Quantum non ideal measurements
Jean-Michel Courty, Francesca Grassia, Serge Reynaud
We analyse non ideal quantum measurements described as scattering processes providing an estimator of the measured quantity. The sensitivity is expressed as an equivalent input noi…

Thermal and quantum noise in active systems
Jean-Michel Courty, Francesca Grassia, Serge Reynaud
We present a quantum network approach to the treatment of thermal and quantum fluctuations in measurement devices. The measurement is described as a scattering process of input flu…
