Quantum random number generators (QRNGs) produce random numbers based on the intrinsic probabilistic nature of quantum mechanics, making them true random number generators (TRNGs). In this paper, we design and fabricate an embedded QRNG that produces random numbers based on fluctuations of spontaneous emission and absorption in a Light-Emitting Diode (LED). To achieve a robust and reliable QRNG, we compare some usual post-processing methods and select the finite impulse response (FIR) method for a real-time device. This device could pass NIST tests, the generation rate is 1 Mbit/s and the randomness of the output data is invariant in time.
