Superconducting Silicon-photonic Chip Developed For Quantum Communication Online

: By using a traveling-wave configuration rather than normal incidence, the SNSPDs achieve on-chip detection efficiencies exceeding 90%.

: These chips are fabricated using standard CMOS industry processes , enabling mass production and large-scale industrialization. : By using a traveling-wave configuration rather than

The chip leverages the Silicon-on-Insulator (SOI) platform for its dense optical components, including waveguides, Bragg filters, and ring resonators. and ring resonators.
