Quantum materials are materials with unique electronic, magnetic or optical properties, which are underpinned by the behavior of electrons at a quantum mechanical level. Studies have showed that interactions between these ...
Recent advances in spontaneous parametric down-conversion (SPDC)-based quantum light sources based on two-dimensional layered materials have been made by a team led by Prof. Ren Xifeng from the University of Science and Technology ...
