Superconducting Silicon-photonic Chip Developed For Quantum Communication Link

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

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

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