Editing Certified finite randomness expansion (section)

==Further Information==
* [https://www.nature.com/articles/nature09008 Pironio et. al.] implement the protocol using two ionic Yttrium qubits, separated by a distance of <math>1</math>, and a uniform probability distribution (i.e. <math>P(x,y)=\frac{1}{4}</math>).  Over the course of one month, they were able to produce <math>n=3016</math> entanglements and recorded a correlation of <math>\hat{I}=2.414</math>; implying at least 42 new random qubits had been produced with a confidence of 99%. The seed used in the experiment was generated from a combination of sources: radioactive decay, atmospheric noise and network activity on a remote computer.
* The protocol presented here implements the simplest design choices throughout. It is possible to use arbitrary Bell inequalities (rather than the CHSH inequality), to use the seed to generate <math>x_i</math> and <math>y_i</math> from some joint probability distribution <math>P(x,y)</math>, and to contsruct the protocol with more than two devices.
