Abstracts:
Lithium niobate on insulator (LNOI) is a promising platform for integrated quantum photonics because of its low optical loss and high-speed electro-optic modulation capabilities. This presentation introduces two recent advances based on LNOI technology: on-chip quantum key distribution (QKD) over field-deployed fiber networks and a photonic variational quantum eigensolver (VQE) implemented on an integrated quantum processor. The QKD system demonstrates secure quantum communication in a practical network environment, while the VQE platform achieves molecular ground-state energy estimation with chemical accuracy using programmable ququart photonic circuits. These results demonstrate the potential of lithium niobate photonics as a unified platform for future quantum communication and quantum computing technologies.
