Abstract: A multiple output quantum random number generator coherently measures an optical source noise and outputs a random number sequence based on the independent and coherent measurement of optical source noise. Therefore, it is possible to output a random number sequence at a high speed and to perform multiple outputs.
Abstract translation: 多输出量子随机数发生器相干地测量光源噪声，并基于光源噪声的独立和相干测量输出随机数序列。 因此，可以高速输出随机数序列并执行多个输出。

Abstract: Provided herein are a multi-channel receiver optical sub-assembly and a manufacturing method thereof. The multi-channel receiver optical sub-assembly includes a PLC chip having a first side into which an optical signal is received and a second side from which the received signal is outputted, with an inclined surface formed on the second side of the PLC chip at a preset angle, a PD carrier bonded onto the PLC chip and made of a glass material, and an SI-PD bonded onto the PD carrier, a lens being integrated therein. The PLC chip, the PD carrier, and the SI-PD are passively aligned by at least one alignment mark and then are bonded.
