Superconducting Silicon-photonic Chip Developed For Quantum Communication -

: Researchers have successfully integrated Superconducting Nanowire Single-Photon Detectors (SNSPDs) directly onto silicon waveguides.

: These chips are fabricated using standard CMOS industry processes , enabling mass production and large-scale industrialization.

A significant advancement enabled by this chip is the of time-bin encoded qubits.

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