A brief history of ghost imaging
November 20th, 2024
Ghost imaging, one of the first imaging techniques using quantum light, has captivated researchers since its inception in the mid-1990s. The concept of ghost imaging was first demonstrated in 1995 by
Tailoring Quantum States with Aperiodic Poling
October 14th, 2024
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 used for numerous
Quasi phase matching with periodic poling
September 11th, 2024
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 such states is spontaneous
Introduction to spatial entanglement in SPDC
July 10th, 2024
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
