DESCRIPTION:Fundamental to integrated photonic quantum computing is an on-
 chip method for routing and modulating quantum light emission. We demonstr
 ate a hybrid integration platform consisting of arbitrarily designed waveg
 uide circuits and single photon sources. InAs quantum dots (QD) embedded i
 n GaAs are bonded to an SiON waveguide chip such that the QD emission is c
 oupled to the waveguide mode. The waveguides are SiON core embedded in a S
 iO2 cladding. A tuneable Mach Zehnder modulates the emission between two o
 utput ports and can act as a path-encoded qubit preparation device. The si
 ngle photon nature of the emission was verired by an on-chip Hanbury Brown
  and Twiss measurement.
