Sub shot-noise fluctuations in the intensity sum of two coupled beams
نویسندگان
چکیده
A quantum analysis of intensity fluctuations for the above-threshold parametric four-wave mixing in a cavity, driven by two laser fields, is presented. A new possibility for the reduction of quantum fluctuations below the shot-noise level in the sum of intensities of two cavity-output coupled beams at the driving field frequencies is predicted. The calculation of the corresponding interbeam second-order correlation function displays photon anticorrelation.

Noise characteristics of correlated two-photon production via parametric down-conversion
This paper gives a review of the phase and intensity quantum correlation between two photons in the process of optical parametric down-conversion (OPDC). Special emphasis is on the squeezed spectrum and squeezed intensity fluctuations in non-degenerate OPDC above threshold. Several experimental results of squeezed spectra and sub shot-noise intensity fluctuations are presented. PACS number(s): ...
متن کاملSub-shot-noise phase quadrature measurement of intense light beams.
We present a setup for performing sub-shot-noise measurements of the phase quadrature of intense pulsed light without the use of a separate local oscillator. A Mach-Zehnder interferometer with an unbalanced arm length is used to detect the fluctuations of the phase quadrature at a single sideband frequency. With this setup, the nonseparability of a pair of quadrature-entangled beams is demonstr...
متن کاملSingle-Molecule Sensitivity in Optical Absorption at Room Temperature
Sensitive detection of condensed matter is of utmost importance in fundamental research as well as cutting-edge applications such as molecular analytics and diagnostics. Until very recently, all existingmethods for the detection of single molecules at room temperature have required highly efficient fluorophores. Here, we demonstrate, for the first time, that single molecules can also be detecte...
متن کاملTwin-beams Statistics for Strong Pumping
Twin beams generated by cw optical parametric oscil lators (OPO) show intensity difference quantum noise reduction below the shot-noise level (SNL) as predicted by Reynaud et al. [1] and proved experimentally in dif ferent configurations [2], At powers higher than four times the threshold also the single beam intensity noise should reduce below SNL in some frequency range [3], an effect compe...
متن کاملTransfer of intensity quantum correlation with twin beams.
We demonstrate experimentally a protocol of transferring nonclassical quantum properties using two pairs of quantum-correlated twin beams in the continuous variable regime. The intensity quantum correlation from one twin beam is transferred to two initially independent idler beams with the help of a displacement transformation. It makes two originally independent beams exhibit an intensity quan...
