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 generates the entangled photon pairs with conserved energy and momentum, so that the quantum correlation in space and time is encoded. Such a property enables a quantum advantage that overcomes the diffraction limit of classical pulses in the field of imaging and det...
