Quantum random number generators (QRNG) based on amplified spontaneous emission (ASE) are known to achieve multi-gigabit-per-second rates through high-speed sampling of intensity and phase fluctuations. Two popular implementations of these QRNGs are based on balanced detection of ASE-ASE and ASE-Laser beating. The high QRNG rates reported so far however come at the price of increased ... https://www.roneverhart.com/Burl-Audio-B2-Bomber-ADC-2-channel-AD-Converter-p17722/
