QRNG

An Arduino Quantum Random Number Generator

Usage

This project is a simple Quantum Random Number Generator. It was tested on an Arduino Uno R3, but similar boards should also work. To run this program, you will need one of the following: the online Arduino IDE (here), the desktop Arduino IDE, or another editor like VS Code with the appropriate extensions. First build the physical circuitry and connect it to the arduino. All parts can be obtained off Amazon. Compile and upload the sketch to your board via USB, and then open a serial monitor to capture output.

Output

The example script continuously prints out random 0/1 bits to the serial monitor obtained from the Quantum::rand_bit() function in loop().

Example:

10101001010100010011100011110101...

By adapting the call to be Quantum::rand<T>() where T is a C++ integral type (e.g. int, long, unsigned int, etc...) or a bool, values of type T made up of random bits may also be obtained. Note that this method works for obtaining random char's; however, they can take any ASCII value and are not guaranteed to be printable characters. To generate random strings, it is advised to take a series of random integers scaled to the indices of a const char* containing acceptable characters and use the values at those scaled integers to select resulting values.
