Integrated photonics for trapped ion quantum information experiments at Sandia National Laboratories

Abstract

As trapped ion systems add more ions to allow for increasingly sophisticated quantum processing and sensing capabilities, the traditional optical-mechanical laboratory infrastructure that make such systems possible are in some cases the limiting factor in further growth of the systems. One promising solution is to integrate as many, if not all, optical components such as waveguides and gratings, single-photon detectors, and high extinction ratio optical switches/modulators either into ion traps themselves or into auxiliary devices that can be easily integrated with ion traps. Here we report on recent efforts at Sandia National Laboratories to include integrated photonics in our surface ion trap platforms.

Development of Grating for the Optical Addressing of Sr+ Ions With Data Analysis Techniques

“…multi-ion quantum logic gates, with direct fibre coupling on multiple channels [5]. Recently, Sandia National Laboratory reported integration of SiPh components on surface ion trap, including waveguides, grating couplers, optical modulators, and single-photon avalanche detector (SPAD) for quantum devices, including quantum computer and quantum clock [6].…”
