Author: Ronen Shekel Even the most stable laser isn’t perfectly quiet. The fact that light comes in discrete photons introduces statistical fluctuations known as shot noise, leading to the standard quantum...
Dispersion cancellation of spectrally entangled photons Author: Ronen Shekel Spontaneous parametric down-conversion (SPDC) is a cornerstone of quantum optics, enabling the generation of entangled photon pairs with remarkable properties....
What is sPPKTP and why did we develop it? Author: Ori levin At Raicol, as a world leader in the manufacture of PPKTP, our goal is to support...
Author: Dr. Noa Voloch Bloch and Ori Levin Raicol, a renowned leader in PPKTP manufacturing, is committed to propelling the quantum industry forward through state-of-the-art solutions. Over the past...
Author: Ronen Shekel Quantum and classical ghost imaging Ghost imaging, one of the first imaging techniques using quantum light, has captivated researchers since its inception in the mid-1990s. The...
Author: Ronen Shekel In a previous post, we talked about how periodic poling provides quasi-phase-matching, its various benefits, and the control it provides over different SPDC parameters. SPDC light is...
Using the Hog-Ou-Mandel effect for imaging The Hong-Ou-Mandel (HOM) effect is a cornerstone of modern quantum optics. Originally proposed and demonstrated in 1987 by Chung-Ki Hong, Zhe-Yu Ou, and...
Quasi phase matching with periodic poling The generation of pure nonclassical states of light is one of the most important goals of optical quantum information science. A popular...
Introduction to Spatial Entanglement in SPDC One of the most remarkable features of quantum theory is entanglement, where quantum systems show nonlocal correlations between particles or photons that are...
Induced coherence and imaging with undetected photons One of the most beautiful experiments with SPDC light is that of induced coherence. It has originally been demonstrated and analyzed by...
