A Quantum Magic 8-Ball Web App Uses a Homemade Random Number Generator
Researcher and engineer David Noel Ng built a device that generates random numbers from photon detection and created a web app called A Quantum Magic 8-Ball. The app randomly selects one of 20 pre-written answers using the quantum random numbers. The device uses an ultraviolet LED, a beam splitter, and photomultiplier tubes to read photon paths as coin tosses.
