This research develops a quantum transducer, a device that connects quantum computers to fiber optic networks. By converting quantum electrical signals into optical signals at cryogenic temperatures, the technology could enable scalable quantum networking and distributed quantum computing, providing a critical foundation for future large-scale quantum systems and quantum internet infrastructure.

This research develops photonic integrated circuits that compute with light instead of electrons. The team built the first on-chip all-optical transistor, enabling ultra-fast optical processors and neural networks that can outperform electronic hardware by orders of magnitude. The work moves us toward practical, high-speed photonic computing for everyday devices.
