Quasiphasematched concurrent nonlinearities in periodically poled KTiOPO_4 for quantum computing over the optical frequency comb

Quantum Physics 2015-05-14 v1

Abstract

We report the successful design and experimental implementation of three coincident nonlinear interactions, namely ZZZ ("type-0"), ZYY (type-I), and YYZ/YZY (type-II) second harmonic generation of 780 nm light from a 1560 nm pump beam in a single, multigrating, periodically poled KTiOPO_4 crystal. The resulting nonlinear medium is the key component for making a scalable quantum computer over the optical frequency comb of a single optical parametric oscillator.
