Abstract

We experimentally realized a chip-based source-independent QRNG. The source-independent scheme provides a solution for the balance between the practical and device-independent QRNGs, which closes the security loopholes from the source, and can be easily realized with respect to the device-independent scheme based on loophole-free Bell test. For the measurement part, the imperfections of the detector are modeled and the practical loopholes in receiver side are thus closed. For the producibility, we use the Silicon-On-Illustrator (SOI) platform to integrate the optical path and detectors on chip. In this way, except for the local oscillator source, all the devices required by our QRNG scheme are integrated on a chip, which significantly promotes the miniaturization and scaling capabilities. The final generation rate is 15.6 Gbps, and the ﬁnal random numbers well pass all the test items of NIST statistical tests, which demonstrates the practicability of a QRNG with source loophole-free, complete practical receiver modeling and chip-based devices.
