摘　　要：Photonics is poised to play a unique role in quantum technology for computation,communications and sensing.Meanwhile,integrated photonic circuits-with their intrinsic phase stability and high-performance,nanoscale components-offer a route to scaling.However,each integrated platform has a unique set of advantages and pitfalls,which can limit their power.So far,the most advanced demonstrations of quantum photonic circuitry has been in silicon photonics.However,thin-film lithium niobate(TFLN)is emerging as a powerful platform with unique capabilities;advances in fabrication have yielded loss metrics competitive with any integrated photonics platform,while its large second-order nonlinearity provides efficient nonlinear processing and ultra-fast modulation.In this short review,we explore the prospects of dynamic quantum circuits-such as multiplexed photon sources and entanglement generation-on hybrid TFLN on silicon(TFLN/Si)photonics and argue that hybrid TFLN/Si photonics may have the capability to deliver the photonic quantum technology of tomorrow.
