Abstract

We route the single photons from a trapped barium ion in a nanophotonic circuit. For this routing, we first generate C-band telecom single photons from barium ion which makes them compatible with the silicon-nitride photonic foundry. Then using the thermo-optic property of silicon-nitride, we switch the single photons in a Mach-Zehnder interferometer controlling the current of the phase-shifter. These results could enable a new generation of compact and reconfigurable integrated photonic devices that can serve as efficient quantum interconnects for quantum computers and sensors.
