New technique for creation of entangled photon states

Members of the Faculty of Physics at the Lomonosov Moscow State University have elaborated a new technique for creating entangled photon states. They have described their research in an article published in the journal Physical ...

Super-resolved coherent Raman spectroscopy with quantum light

In recent years, entangled photons—a popular quantum light source—have been widely used in quantum imaging, optical interferometry, quantum computing, quantum communication, and other fields. Spontaneous parametric down-conversion ...

Understanding spectral properties of broadband biphotons

Advances in quantum optical technologies require scientists to control and exploit the properties of so-called biphotons. Biphotons occur when two photons become 'quantum-entangled' - spatially separate entities whose individual ...
