Direct observation of nonclassical photon statistics in parametric down-conversion.

چکیده
We employ a high quantum efficiency photon number counter to determine the photon number distribution of the output field from a parametric down-converter. The raw photocount data directly demonstrates that the source is nonclassical by 40 standard deviations, and correcting for the quantum efficiency yields a direct observation of oscillations in the photon number distribution.

Direct, loss-tolerant characterization of nonclassical photon statistics.
We experimentally investigate a method of directly characterizing the photon-number distribution of nonclassical light beams that is tolerant to losses and makes use of only standard binary detectors. This is achieved in a single measurement by calibrating the detector using some small amount of prior information about the source. We demonstrate the technique on a freely propagating heralded tw...
متن کاملHow colors influence numbers: Photon statistics of parametric down-conversion
Parametric down-conversion PDC is a technique of ubiquitous experimental significance in the production of nonclassical, photon-number-correlated twin beams. Standard theory of PDC as a two-mode squeezing process predicts and homodyne measurements observe a thermal photon number distribution per beam. Recent experiments have obtained conflicting distributions. In this article, we explain the ob...
متن کاملUltrabroadband direct detection of nonclassical photon statistics at telecom wavelength
Broadband light sources play essential roles in diverse fields, such as high-capacity optical communications, optical coherence tomography, optical spectroscopy, and spectrograph calibration. Although a nonclassical state from spontaneous parametric down-conversion may serve as a quantum counterpart, its detection and characterization have been a challenging task. Here we demonstrate the direct...

Quantum mechanics interprets nonlinear optical processes as physical effects composed of many elementary ‘quantum’ events in which one (several) photon is annihilated and several (one) photon emerge [1]. This behavior of nonlinearly interacting physical systems is completely unusual in classical physics and lies in heart of nonclassical-light generation. Generation of correlated photon pairs in...
متن کاملDispersion in Femtosecond Entangled Two-Photon Interference
Significant consideration has recently been given to the process of spontaneous parametric down-conversion in nonlinear crystals pumped by cw lasers [1–4]. The nonclassical properties of entangled two-photon light generated by this process have been used in many experimental schemes to elucidate distinctions between the predictions of classical and quantum physics [5]. Coincidence-count measure...
