Photonic chip for high-speed secure communication


Summary

This technology is a photonic chip interferometer that uses a series of polarizing beamsplitters and other optical components to generate and measure the polarization and spatial mode degrees of freedom of hyperentangled photons. Measurement of these properties enables high-rate quantum key distribution (QKD) for secure communication and reliable generation of hyperentangled photons for other quantum computing applications.
