In optics, when a collection of nonlinear processes act together on a pump beam, the resulting spectral broadening of the original pump beam gives rise to a supercontinuum. Supercontinuum sources for optical coherence tomography ...
There has been an interesting debate on the quantum versus classical origin of ghost imaging in thermal light. To clarify this quantum-classical dilemma, Lixiang Chen at Xiamen University of China formulated a density matrix ...
