Abstract: B26.00007 : Quantum non demolition parity measurements of itinerant microwave fields
12:27 PM–12:39 PM
Defining a mode to be characterized by the temporal shape of a displacement field added onto it, we recover its Wigner function without making use of reconstruction or maximum likelihood methods. We present results of this phase space tomography method for propagating fields for various classical and quantum input fields.
The non demolition character of the measurement also allows for heralding highly non-classical states of light, such as multi-photon cat states, which are relevant for quantum information processing.
