Title :
Erasing frequency distinguishability using single-photon up-conversion

Abstract :
The frequencies of two frequency non-degenerate single photons were converted to the same frequency by using the sum frequency generation process in periodically poled lithium niobate waveguides, while maintaining their temporal indistinguishability. As a result, the two converted photons exhibited a non-classical dip in a Hong-Ou-Mandel quantum interference experiment.
