Review Questions
How do environmental factors influence the performance of QRNGs?
Environmental factors such as temperature, electromagnetic interference, and humidity can significantly affect the performance of QRNGs. For instance, temperature changes may alter optical components’ behavior, leading to variations in randomness. Additionally, electromagnetic interference can disrupt the sensitive quantum measurements necessary for generating true random numbers, potentially biasing the results. Understanding these influences is crucial for developing reliable QRNG systems.
