隨機亂數在眾多領域中具有廣泛的應用，從量子密鑰分發、經典密碼學到賭博遊戲及樂透等娛樂行業，隨機數都扮演著重要角色。在量子電腦發展大幅進步的情況下，便有利用物理性質生成的隨機亂數，被認為是「真正的」隨機數。
真隨機亂數產生器 (true random number generators) 可以透過探測如硬體雜訊、系統熱雜訊和量子性質等物理現象來生成不可被預測的「真隨機亂數」。其中，利用真空態波動量子現象中的機率性質來作為隨機數來源，可以確保生成的隨機數具有高度不可預測性且有真隨機性，稱為量子隨機亂數產生器 (QRNG)。
本研究利用平衡零差檢測 (Balance Homodyne Detection) 方法探測室溫下之真空態量子相位變異來開發出積體化QRNG，產生速率約70 Mbps，並且產生之隨機亂數通過NIST統計測試，並結合自行開發之自動平衡零差檢測系統，利用自動化控制光晶片來達到平衡零差檢測的效果，未來結合FPGA可以更容易實現高效率之多通道積體化QRNG之應用。

Random numbers have extensive applications across various fields, from quantum key distribution and classical cryptography to gambling games and lotteries in the entertainment industry, where they play a crucial role. With the significant advancements in quantum computing, random numbers generated using physical properties are considered to be "true" random numbers.
True Random Number Generators (TRNGs) can produce unpredictable "true" random numbers by detecting physical phenomena such as hardware noise, thermal noise in systems, and quantum properties. Among these, using the probabilistic nature of quantum fluctuations in the vacuum state as a source of randomness ensures that the generated random numbers have a high degree of unpredictability and true randomness. This method is referred to as a Quantum Random Number Generator (QRNG).
This study leverages Balanced Homodyne Detection to measure the quantum phase variance of the vacuum state at room temperature, developing an integrated QRNG that achieves a generation rate of approximately 70 Mbps. The generated random numbers successfully pass the NIST statistical tests. Additionally, by combining a self-developed automatic balanced homodyne detection system, which utilizes automated control of the photonic chip to achieve balanced homodyne detection, future integration with FPGA technology will facilitate the implementation of highly efficient multi-channel integrated QRNGs.
