Tomographic measurement of joint photon statistics of the twin-beam quantum state
نویسندگان
چکیده
We report the first measurement of the joint photon-number probability distribution for a two-mode quantum state created by a nondegenerate optical parametric amplifier. The measured distributions exhibit up to 1.9 dB of quantum correlation between the signal and idler photon numbers, whereas the marginal distributions are thermal as expected for parametric fluorescence.

Statistics of Exciton Emission in a Semiconductor Microcavity: Detuning and Exciton-Exciton Effects
We consider the interaction of quantum light with an ideal semiconductor microcavity. We investigate photon statistics in different conditions and the presence of detuning and exciton-exciton interaction. We show that in the resonant interaction and absence of the exciton-exciton interaction, the state of the whole system can be considered as coherent state. According to our results, it turns...
متن کاملPhoton Counting Sampling of Phase Space
First complete experimental characterisation of the quantum state of a single light mode was demonstrated by Smithey et al. In their work, numerical tomographic algorithms were applied to reconstruct the Wigner function from homodyne statistics. Recently, a novel scheme for measuring the quantum state of light by photon counting has been proposed. In contrast to tomographic techniques, the newl...
متن کاملJoint multipartite photon statistics by on/off detection.
We demonstrate a method to reconstruct the joint photon statistics of two or more modes of radiation by using on/off photodetection performed at different quantum efficiencies. The two-mode case is discussed in detail, and experimental results are presented for the bipartite states obtained after a beam splitter fed by a single photon state or a thermal state.
متن کاملA Non-Demolition Photon Counting Method by Four-Level Inverted Y-Type Atom
The semi-classical model of atom-field interaction has been fully studied for some multilevel atoms, e.g. Vee, L, Cascade X , Y, and inverted Y and so on. This issue is developed into the full-quantum electrodynamics formalism, where the probe and coupling electromagnetic fields are quantized. In this article, we investigate the full-quantum model of absorption and dispersion spectrum of trappe...
متن کاملDynamical evolution of nonclassical properties in cavity quantum electrodynamics with a single trapped ion
In this paper, by considering a system consisting of a single two-level trapped ion interacting with a single-mode quantized radiation field inside a lossless cavity, the temporal evolution of the ionic and the cavity-field quantum statistical properties including photon-counting statistics, quantum fluctuations of the field quadratures and quantum fluctuations of the ionic dipole variables are...
