Wigner function of pulsed fields by direct detection.
نویسندگان
چکیده
We present the reconstruction of the Wigner function of some classical pulsed optical states obtained by direct measurement of the detected-photon probability distributions of the state displaced by a coherent field. We use a photodetector endowed with internal gain, which is operated in the non-photon-resolving regime. The measurements are performed up to mesoscopic intensities (up to more than 30 photons per pulse). The method can be applied to characterize nonclassical continuous-variable states.

Probing the negative Wigner function of a pulsed single photon point by point.
We investigate quantum properties of pulsed light fields point by point in phase space. We probe the negative region of the Wigner function of a single photon generated by the means of waveguided parametric down conversion. This capability is achieved by employing loss-tolerant photon-number resolving detection, allowing us to directly observe the oscillations of the photon statistics in depend...

متن کاملSelf-consistent phase determination for Wigner function reconstruction
We present the reconstruction of the Wigner function of a classical phasesensitive state, a pulsed coherent state, by measurements of the distributions of detected-photons of the state displaced by a coherent probe field. By using a hybrid photodetector operated above its photon-resolving regime, we obtained both the statistics at different values of the probe field and the values of the probe ...
متن کاملDirect measurement of the Wigner function by photon counting
Among many representations of the quantum state, the Wigner function offers an appealing possibility to describe quantum phenomena using the classical-like concept of phase space [1]. The Wigner function provides complete information on the state of a system, and it allows one to evaluate any quantum observable by phase space integration with an appropriate Wigner-Weyl ordered expression. Recen...
متن کاملUltrasensitive pulsed, balanced homodyne detector: application to time-domain quantum measurements.
A pulsed, balanced homodyne detector has been developed for precise measurement of the electric field quadratures of pulsed optical quantum states. A high level of common mode suppression (>85 dB) and low electronic noise (730 electrons per pulse) provide a signal-to-noise ratio of 14 dB for measurement of the quantum noise of individual pulses. Measurements at repetition rates as high as 1 MHz...
