Quantum Coin Toss

An easy-to-perform quantum mechanics-based alternative to tossing a coin

import chances
import random
# use pseudo randomness to pick either even or odd
random.choice(['even', 'odd'])
# use pseudo randomness to pick either head or tail
random.choice(['heads', 'tails'])
# set the `max` and `n` values for the random generator
rand = chances.Randomizer(1000000, 1)
# use quantum mechanical randomness to pick a number
rand.quantum()

In the first two lines of the actual code, we decide if even or odd will be head or tails.

In the third line, we initiate the random number generator to give a single value that is not greater than 1,000,000.

In the fourth line, we do the actual pick from a real-time stream of quantum mechanically appearing numbers.

Putting it all together, if we get as outputeven from the first line, and heads from the second line, and 20301 from the fourth line, we then know we have tails .

To express the some properly in a function that directly answers the question between two arbitrary alternatives:

    '''Quantum coin tosser
    a | str or int or list or dict | any value or set of values
    b | str or int or list or dict | any value or set of values
