Abstract

Frequency-entangled photon pairs are attracting lots of attention due to their potential for novel quantum applications, namely quantum sensing. In the first part, we report the efficient spatial separation of collinearly emitted broadband frequency-correlated photon pairs. We find that broadband photon pairs with a bandwidth of about 90 nm can be efficiently separated using time-reversed Hong-Ou-Mandel (HOM) interference. In the second part, we report the application of such broadband frequency entangled photons for quantum sensing applications.
