===Magic States===
It is any state that, if you have an unlimited supply of them, can be used to give you universal quantum computation when used in conjunction with perfect Clifford operations. The standard example is that if you can produce the state <math>(|0 \rangle +e^{i \pi/4}|1 \rangle )/ \sqrt{2}</math>, then you can combine this with Clifford operations in order to apply a T gate, and we know that T+Clifford is universal.
