Abstract

This paper demonstrates a highly secure quantum random number generator (QRNG) using a perovskite light-emitting diode (PeLED) as the light source. The PeLED's ease of fabrication and excellent optical properties make it a cost-effective and efficient option for generating random numbers certified secure against eavesdropping, following a quantum measurement-device-independent scenario. Achieving a generation rate exceeding 10 Mbit/s, comparable to commercial devices, highlights the potential of PeLEDs for quantum information tasks and future quantum technology applications.
