Breaking Bell's Inequality with Monte Carlo Simulations in Python

2024122 points59 comments Math & Algorithms details

The article explains the Bell inequality using Monte Carlo simulations in Python, and shows how non-local action-at-a-distance can be used to break it with entangled qubits.

Randomness extractors: making fair coins out of biased coins

2024105 points52 comments Math & Algorithms details

I discuss various models of biased bit sequences, and how to extract uniform random (or close to it) output bit sequences from them, illustrated with Python code.
