Hessian polyhedron code[1,2] 

Also known as Schläfli configuration.

Description

Spherical \((6,27,3/2)\) code whose codewords are the vertices of the Hessian complex polyhedron and the \(2_{21}\) real polytope. Two copies of the code yield the \((6,54,1)\) double Hessian polyhedron (a.k.a. diplo-Schläfli) code. The code can be obtained from the Schläfli graph [3; Ch. 9]. The (antipodal pairs of) points of the (double) Hessian polyhedron correspond to the 27 lines on a smooth cubic surface in the complex projective plane [47].

See [8][3; Exam. 1.2.5] ([9; pg. 119]) for a real (complex) realization of the 27 codewords.

Protection

The Hessian polytope code has degree \(d=2\) and saturates the absolute bound [3].

Realizations

Quantum mechanical SIC-POVMs [10].

  • \(E_6\) root lattice — The 27 Hessian polyhedron codewords are intimately related to the \(E_6\) Lie group [12].
  • \(E_6\) lattice-shell code — Double Hessian polyhedron codewords form the minimal lattice-shell code of the \(E_6^{\perp}\) lattice [13].
  • Rectified Hessian polyhedron code — The (rectified) Hessian polyhedron is an analogue of a (octahedron) tetrahedron in 3D complex space, while the double Hessian polyhedron is the analogue of a cube [9; pg. 127]. The rectified and double Hessian polyhedra are dual to each other, just like the octahedron and cube. Moreover, the double Hessian consists of two Hessians, just like the cube can be constructed with two tetrahedra.
  • Hessian QSC — The Hessian QSC is the quantum generalization of the classical Hessian polyhedron code.
