And in terms of Shannon entropy, the original two bits have 0.469 bits of entropy each, and the resulting XORd bit has 0.68 bits of entropy. So this extractor

And in terms of Shannon entropy, the original two bits have 0.469 bits of entropy each, and the resulting XORd bit has 0.68 bits of entropy. So this extractor is far from ideal.
