Towards meeting the strict demands of practical quantum networks, we leverage coherent energy redistribution for noise-tolerant quantum signal processing. We demonstrate the enhancement of noisy biphoton coincidence-to-accidental ratios by up to 3.8

The electro-optical coefficient r33 of a novel ferroelectric thin film (Calcium Barium Niobate) is estimated using a single beam set-up in a reflection geometry. Our measures show that the value of r33 in this material is as large as 100 pm/V.
