We've discussed random number generation schemes here before. They
are important to simulations, experimental design, gambling devices,
and cryptography. Here is one that works at 1.7 gigabits per second
(Gbps):

The above scheme works based on sensing a potential, specifically a
photodetector potential, which is a process subject to hysteresis,
and thus bias, when converting two ranges of potentials to
corresponding bit values. As discussed before, there is a solution
available for this bias problem:
