Noise characteristics of correlated two-photon production via parametric down-conversion
نویسنده
چکیده
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): 42.50.Lc , 42.50.Dv, 42.65.Ky

One-Way Autocompensating Quantum Cryptography via Auto-Phase-Matched Spontaneous Parametric Down-Conversion
We present a new quantum cryptography implementation that uses frequency-correlated photon pairs to combine one-way operation with an autocompensating feature that has hitherto only been available in implementations that require the signal to make a round trip between the users. Furthermore, we describe a new scheme for creating frequency-correlated photon pairs (auto-phase-matched spontaneous ...
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 کاملPhoton pair generation in a silicon micro-ring resonator with reverse bias enhancement.
Photon sources are fundamental components for any quantum photonic technology. The ability to generate high count-rate and low-noise correlated photon pairs via spontaneous parametric down-conversion using bulk crystals has been the cornerstone of modern quantum optics. However, future practical quantum technologies will require a scalable integration approach, and waveguide-based photon source...

We propose a simple scheme to produce the polarization entangled photon pairs without the type II phase match. The same scheme can also be used to produce the macroscopic entangled photon states in both photon number space and the polarization space(A. scheme in quantum key distribution are discussed. As it is general believed that, quantum entanglement plays a fundamentally important role in t...
