\(((7,2,3))\) Pollatsek-Ruskai code[13] 

Also known as \(((7,2,3))\) icosahedral code.

Description

Seven-qubit PI code that realizes gates from the binary icosahedral group transversally. Can also be interpreted as a spin-\(7/2\) single-spin code. The codespace projection is a projection onto an irrep of the binary icosahedral group \(2I\).

In terms of Dicke states, the unnormalized logical states of one version [3] of this code are \begin{align} \begin{split} |0_{L}\rangle&\propto15|D_{0}^{7}\rangle+3\sqrt{35}|D_{4}^{7}\rangle\\&\quad+\sqrt{105}\;|D_{2}^{7}\rangle-3\sqrt{35}|D_{6}^{7}\rangle\,,\\|1_{L}\rangle&\propto X^{\otimes7}|0_{L}\rangle\,. \end{split} \tag*{(1)}\end{align}

Transversal Gates

Binary icosahedral group \(2I\) gates can be realized transversally [3].
