- Abstract: Progress in integrated photonics enables combining several elementary
functions on single substrates for realizing advanced functionnalized chips. We
report a monolithic integrated quantum photonic realization on lithium niobate,
where nonlinear optics and electro-optics properties have been harnessed
simultaneously for generating heralded configurable, two-photon states. Taking
advantage of a picosecond pump laser and telecom components, we demonstrate the
production of various path-coded heralded two-photon states, showing 94\% raw
visibility for Hong-Ou-Mandel interference. The versatility and performance of
such a highly integrated photonic entanglement source enable exploring more
complex quantum information processing protocols finding application in
communication, metrology and processing tasks.
