Simple magic state calculations using `Improved Simulation of Stabilizer Circuits'

Abstract

We employed the techniques from [Phys. Rev. A \textbf{70}, 052328 (2004)/arXiv:0406196] to analytically study two set of quantum circuits containing one $T$ gate/magic $|T⟩=\frac{|0⟩+\sqrt{i}|1⟩}{\sqrt{2}}$ state. These include the $T$ state via gate teleportation and magic state injection on the rotated surface code.
