TODO Equations

update mathjax to use commonhtml http://docs.mathjax.org/en/latest/output.html

The Hamiltonian for the ising model is

\begin{equation} H = E = -h\sigma \end{equation}

where \(\sigma \in \{-1,1\}\)

An EPR pair is the state \[\ket{\Phi} = \frac{1}{\sqrt{2}}\pqty{\ket{00}+\ket{11}}\]

The which can be obtained from a Haddamard and CNOT gate: \[H= \frac{1}{\sqrt{2}}\pmqty{1&1\\1&-1}\] \[CNOT= \pmqty{1&0&0&0\\0&1&0&0\\0&0&0&1\\0&0&1&0}\] applied as such \(CNOT((H\ket{0})\otimes\ket{0}) = \ket{\Phi}\) 1
