Abstract
A system includes a classical computing system and one or more quantum computing chips coupled to the classical computing system. The one or more quantum computing chips includes one or more electro-optic devices. Each electro-optic device includes a substrate, a waveguide disposed on top of the substrate, and a layer stack disposed on top of the waveguide and including a plurality of electro-optic material layers interleaved with a plurality of interlayers. Each electro-optic device further comprising a waveguide core disposed on top of a portion of the layer stack. The plurality of interlayers are characterized by a first lattice structure and the plurality of electro-optic material layers are under tensile stress and are characterized by a second lattice structure and crystallographic phase.
