ric down-conversion process with broad phase matching.By utilizing different orders of frequency modes, both degenerate and non-degenerate processes are generated.After passing through low-loss filters, high quality base-band squeezing and EPR pairs with strong entanglement have been observed.This work represents a critical step toward flexible and versatile quantum resource, which will greatly facilitate the development of quantum technology based on squeezed light.
