Tailoring Quantum States with Aperiodic Poling
October 14th, 2024
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 […]
Quasi phase matching with periodic poling
September 11th, 2024
Author: Ronen Shekel The generation of pure nonclassical states of light is one of the most important goals of optical quantum information science. A popular and versatile source for creating […]
Introduction to spatial entanglement in SPDC
July 10th, 2024
Author: Ronen Shekel One of the most remarkable features of quantum theory is entanglement, where quantum systems show nonlocal correlations between particles or photons that are impossible to explain using […]
Using the Hog-Ou-Mandel effect for imaging
June 26th, 2024
Author: Ronen Shekel 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 Leonard Mandel from the […]
Induced coherence and imaging with undetected photons
May 21st, 2024
One of the most beautiful experiments with SPDC light is that of induced coherence. It has originally been demonstrated and analyzed by Zou, Wang, and Mandel in 1991 and is discussed and utilized to this day.
