Integrated Silicon Photonic Quantum Chip Platform and Readout System

Meeting & Discussion

Technology Introduction:
We have developed a novel Si₃N₄-Si quantum photonic platform for continuous-variable (CV) quantum optics operations, which will also be used to implement a quantum random number generation (QRNG) chip. The platform is packaged with a low-noise, high-speed transimpedance amplifier (TIA) circuit board in an enclosure to form a portable readout module for on-board homodyne detection of quantum noise.
Industry Applicability:
CV quantum optics enables room-temperature and deterministic quantum operations, making them ideal for quantum communication, computing, and sensing. Yet, most current systems are bulky and unsuitable for real applications. Our project’s integrated quantum photonics platform addresses this challenge by implementing quantum optics on a chip, delivering a compact, practical, and scalable solution.
